What Sheep? Rediscovering Palm Canyon at Anza Borrego State Park

Palm Canyon Oasis


Date: November 23, 2023
Place: Anza Borrego State Park, Borrego Springs, California
Coordinates: 33.270180, -116.419241
Length: 3.5 miles
Level: moderate

On the morning of Thanksgiving Day we headed to the trailhead of Palm Canyon. On the day before we hiked The Slot. This morning we opened the day with a short visit at the Anza Borrego State Park visitor center where we got some information, then drove to the park's main campground where we had stayed in Christmas of 2012 and parked at the day use area where the trailhead was. It was a lovely day - warm but not hot. The sky featured light feather clouds and the desert featured itself - naked and powerful. 
At Palm Canyon Trailhead

Last time we hiked at Palm Canyon, in December of 2012, we set out to look for bighorn sheep. We didn't find the sheep on that hike then, but we've seen them on other occasions since, so this time I weren't anxious to find them, I was ready to relax and enjoy what the desert had to offer.

Ocotillo is one of the southwest desert unique inhabitants. Beautifully suited for the erratic desert precipitation pattern it spends most of its life bare, photosynthesizing minimally through its stems. When water is available it grows little leaves that are so small they don't really protrude through the thorns. From a distance the ocotillo would look bare still, but fully foliaged, it is much greener than it would otherwise appear. Its most striking transformation the ocotillo does when blooming - it then produces bright red blossoms, and the normally gray-green, well blending in the scenery plant becomes a brilliant advertisement for nectar and pollen goodies, seen far and wide by hummingbirds, sphinx moths, and other pollinators. 
At the end of November, which is when we were there, I expected the ocotillo to be on their most retracted, unfoliaged, semi-dormant stage.The previous summer however, brought some monsoon rains to the desert and many ocotillo responded with sprouting leaves, which they wore still at the time of our visit.
Ocotillo, Fouquieria splensens ssp. splendens

We headed into the trail. The desert mountains loomed ahead of us, serene and dry. Nothing in the scenery suggested that there was water hidden there, an oasis. The creek at the canyon mouth, was dry. 
Almost immediately we had to decide which path to take - the direct trail to the oasis, or the alternative path that followed the southwest side of the wider part of the canyon. We chose to take the alternative route and return by the main trail.

We weren't anxious to see bighorn sheep on this hike, but we did hope to see them, as well as other wildlife. Naturally, we were all very excited when a roadrunner presented itself right at the beginning of our hike.

I was also happy to see a bit of bloom here and there. It was nothing like the mega bloom I saw in Anza Borrego last January, but I loved seeing every brave little flower along the path.
Windmills, Allionia incarnata var. incarnata

The first part of the alternative trail was level and easy. Generally following the path of the wash it stretches on the higher part of the creek bed, cutting through the wide part of the wash before it encloses into a canyon. 

The young chika pointed out the ants for me to look at. We've seen some insects on this hike, and by far and wide the most numerous of them were the harvest ants.

Little by little the trail shifted upward and we were ascending the southern side slope. It wasn't a steep climb, and we walked at a good pace. I was bringing up the rear, pausing every now and then to check out plants of interesting rocks.
Desert Trumpet, Eriogonum inflatum

A mass of large, red boulders loomed ahead of us. The boulders seemed to be blocking the path but when we approached we saw that the trail ascended around and between the boulders. 
 
For small wildlife these boulders were the perfect home and hiding place. Little squirrels feel secure enough to pose openly atop of the boulder, assured that they could dart instantly under cover at the first sign of threat.

Birds too find shelter in these rocks, and one bird that was spotted by my family birders, the rock wren, has this habitat mirrors in its name.

At the top of the ascend I turned and looked back. The climb wasn't hard and up to the boulders it was hardly noticeable that we were gaining elevation, so it surprised me to see how high we were over the campground area where we started our hike. 

There were more wildflowers along the trail. Not many, but certainly many more than I expected to see at this time of year, especially high above the water source. It was interesting that each flowering shrub had only a single or very few flowers, like it was doing it without much enthusiasm. 
Desert Mallow, Sphaeralcea ambigua

I looked up a side tributary wash. It was completely dry and there was no sign of any oasis up the short wash.  
Side Wash

The cacti weren't blooming and I didn't expected them to, not in November. They did look happy, well watered though. I expect this spring there is a major cacti bloom in Anza Borrego. 
Beavertail Cactus, Opuntia sp.

The trail descended mildly towards the creek below. The creek was higher now so we needn't have descended much. The trail was adorned by happy and healthy looking cacti all the way down. A happy and healthy looking sparrow was perched on one cholla cactus, posing for Pappa Quail and theh elder chika. 
Black-throated Sparrow

We reached the creek and the main trail. Logs marked  the trail's boundary, blocking the access to the water at that spot. The log was a perfect place for a fence lizard to sun itself. 
Western Fence Lizard

It was also the first spot on our hike where we saw the flow of the creek, the year-round running creek at Borrego Palm Canyon, that is the lifeline of Borrego Springs. 

From that place there was only one trail leading to the Palm Canyon oasis. At first it was wide, flat, and very comfortable. We picked up our pace, heading northwest towards the oasis.
Palm Canyon Trail

Near the water the cacti made way to other, less prickly plants, such as willow trees and the Emory's daisy, which I already knew well from previous visits at Anza Borrego and other California deserts. 
Emory Rock Daisy, Perityle emoryi

Down at the canyon where the creek had cut through the rock we could see the exposed layers deposited by the ancient sea that used to be here millions of years ago. At the place we saw, the layers were vertical. They sediments weren't deposited in that way of course. It was subsequent geological forces which created these mountains moved and twisted these rocks to their current formation.

We passed another, longer side tributary wash on our left. I looked into it but there too I saw no signs of any water and no oasis.
Side Wash

The Palm Canyon Oasis was visible ahead of us. There was no mistaking in the presence of water there - California fan palms need fresh water, and lots of it, in order to thrive. The size of the palm grove was evident of exactly that - lots of fresh water.

Nearing the oasis the trail became a bit more challenging. It crossed to the northeast side of the creek and from there it was a matter of going around and over large boulders and bushes.

We came down to and through the creek a couple of time on our way. It was lovely seeing the beautiful, healthy looking palms growing right from the water. The dry, old branches created a thick, protective blanket around the palm's trunk. This layer, which is always removed from palms in city landscaping, provides shelter to many wildlife species. The shelter, and also the palms' tiny and sweet date-like berries make the California fan palm a keystone species in the California desert ecology. If these palm disappear, so will the animals that depend on them.
California Fan Palm, Washingtonia filifera

Palm Canyon Creek was still flowing late in November, fed by springs. The flow was very gentle, and noticeable only in places where the water moved through narrow rock straits and dropped down little rock ledges. In wider areas the creek formed calm pools with mirror-perfect reflections.
Reflection

The palms weren't the only trees in the oasis. All along the running part of the creek were arroyo willows, and up by the oasis I saw other water-loving trees such as the cottonwood poplar. 
Fremont Cottonwood, Populus fremontii

As expected, the vegetation got much thicker the closer we got to the oasis. Anna's hummingbirds flew around us, their wings creating the low pitch buzz after which these tiny birds were named. Occasionally these busy birds would sit and pose for the camera.
Anna's Hummingbird

Hummingbirds are suited for drinking nectar from wildflowers but they also hunt for bugs. This is good because this way they don't have to rely on the leaner menu of fall wildflowers.
Wirelettuce, Stephanomeria pauciflora

Once again the trail ascended, this time on the northeast side of the creek. We didn't climb much, just enough to circumvent a pile of large boulders. There were a couple of places where I had to use my hands to climb a ledge. Cushion-like brittle bushes grew in between the boulders. None of them were blooming, but they looked lovely nonetheless.
Brittlebush, Encelia farinosa var. farinosa

We reached the main palm grove and immediately I saw a big change since the last time we were there. In the winter of 2012 the oasis was a thicket of health palms, all with their thick skirts of dry branches. We could go down and sit by the water,and listen to the multitude of birds that hid in the palms. It was there that we had met another family and connected with them for the rest of that trip and after that too, since like us, they had traveled from the Bay Area. Now the palms stood charred and naked, stripped from their skirts by a fire that apparently was ignited by people. It was no longer permitted to go down to the water, and it was clear why.
California Fan Palm, Washingtonia filifera

We could go a bit further through a narrow and low boulder tunnel, and there we sat down for a break and to observe the oasis from a safe (for the trees) distance above.

Information posts told the story of the native people who lived in this place and relied on pretty much any part of the fan palm for their living. They however, knew how to protect and manage their living area, for their existence depended on it.

Where we sat down was a small space, and when other hikers came up and through the boulder tunnel we finished our break and started our way back down.
Desert Lavender, Condea emoryi

I looked up the canyon. There was no evidence of any other oasis, though later I found out that there was another, smaller one behind the curve of the canyon. There was no obvious trail leading upstream but it was clear that people have been going there, scrambling over the rocks and boulders. We weren't going to go there, at least not on this visit.

While we were at the oasis the clouds had gathered. Not thick clouds- we didn't anticipate any rain, but it was enough to darken the view down the canyon.

Once again we scrambled through the rocks and boulders until we reached down to the water. There, the palms were younger, and certainly healthy. I was glad that the habitat had still thriving areas for the wildlife.
Palm Canyon Creek

On our way back we took the direct trail straight down the canyon. The trail was wide and comfortable to walk.
Palm Canyon Trail

A good distance from the oasis I saw another tree that seemed to do well in Palm Canyon. It grew far away from the competitive area that was won by the cottonwood and the fan palms. I didn't identify the species of that tree, and there were only a few of them in that place.

We came upon a trail junction where another trail split off to the east into the desert wilderness. Right at the junction were a few wasps on the ground, eagerly tasting something from the rocks, perhaps some minerals? The wasps didn't show any interest in us but elder chika took the photo from a safe distance.

Down the canyon I spotted some chuparosa bushes. In season, these bushes bloom looks like a brilliant red coat on the plant, and hummingbirds hover around them. Now seeing just this one branch blooming pleased me greatly.
Chuparosa, Justicia californica

Here and there we could see the water flow as the trail neared the creek. Each time the flow looked thinner and thinner, until it reduced to small and stagnant water holes.

Closer to the canyon mouth the trail narrowed and curved around large rocks, rounded by eons of floods pushing and polishing them. Some of these rocks were really pretty.

We were back in the dry area of the canyon where the only greenery was of the creosote bushes and of the tiny leaves of the ocotillo that received a good drink last summer.

The hummingbirds were fine in the dry area as well. They had enough chuparosa flowers and insects to live on.
Anna's Hummingbird

The canyon opened up and for some distance the trail merged with the creek bed, which was completely dry here. The clouds were still gathered above but the sun was poking through a large blue patch in between them.

For the rest of the trail I watched Pappa Quail and the elder chika marching ahead, while I walked slowly with the younger chika, chatting and enjoying the beautiful surrounding.

At the trailhead there is a small, man made pond, which is a sanctuary for the rare and endangered desert pupfish. Pupfish are ancient survivors from the immemorial time in which the area was covered with water. Now they remain in the few ponds and water holes left in the desert, like islands remnant of another world.

I saw the fish, but I was unable to take any descent photo of them - they were well hidden within the rushes. I settled on photographing the many honey bees that came to drink from the pond.
Honey Bees

We didn't see any bighorn sheep on this hike but I loved it, regardless. Palm Canyon and The Slot (which we hiked the day before) were second time hikes for us. Our next hike later today would be to Pictograph Canyon, which would be a first time hike for us. I was excited.

Sqeezing Through the Tight Spot Once More: Hiking The Slot at Anza Borrego State Park

The Slot

 
Date: November 22, 2023
Place: Anza Borrego State Park, Borrego Springs, California
Coordinates: 33.182012, -116.214109
Length: 2.8 miles
Level: moderate


Pappa Quail haven't been to Anza Borrego since 2012, and since desert bloom wasn't on our agenda for this visit, he wanted to revisit some of the trails that we've hiked then. I had visited Anza Borrego on the previous spring but then I did focus on the desert super bloom and hiked where the bloom was, so I too was happy to revisit some of the fun trails I remembered from our 2012 trip. 
We arrived at Anza Borrego in the afternoon, after a fairly dry and somewhat disappointing (birding-wise) visit at the Sonny Bono National Wildlife Refuge in the south of Salton Sea. We had enough day light hours left for a short hike and Pappa Quail suggested that we'd hike The Slot. We all agreed immediately - we all remembered fondly that hike as being much fun and not difficult at all. It was easy to find the coordinates - I had published them here on my blog post of our 2012 hike.  
Even before going on the dirt road that leads to The Slot the elder chika found a bird and asked that we'd stop to take a photo. 
House Finch (before the hike)

When we arrived at the small parking area of The Slot we saw that we weren't alone there - a number of cars were already parking there. We found a spot, parked, and looked around. The area was of low hills with disperse vegetation comprised of mostly creosote and ocotillo bushes, and dry grasses. The canyon itself wasn't visible from the parking area.
At the trailhead

The trailhead wasn't marked very clearly and our memory of the hike 11 years ago didn't kick in yet so we did a little scouting upstream before we found where to descend into the slot canyon. We encountered a few other hikers who seemed at loss as to where they should be going. 
Our hike as captured by my GPS

 Going down into the slot canyon meant going into early dusk. It was about 4 pm when we started our hike and the late afternoon sun no longer penetrated the canyon bottom. 

In places at the higher part of The Slot the canyon opened up a bit to let more sunshine in. A desert holly growing on the south-facing slope shone brightly in the light like the biblical burning bush. No, I did not hear any voices coming out of it. 
Desert Holly, Atriplex hymenelytra

Very quickly we were engulfed by the canyon, as the rock walls closed in and towered over us. Not too high at first - the band of bright blue sky was still wide enough above us, and there was plenty of light yet to see the fine details of the layered rock sediments through which the canyon was cut.
The Slot

I am by no means a geology specialist, but rock formations and geological processes have always fascinated me. One of the joys of hiking in the desert is in seeing the earth naked - her rocky bones uncovered with continuous vegetation cover, her bones rugged and sharp, not softened and rounded by frequent precipitation and runoff.
Rock coloration

The trail isn't designated as a one-way. I intended to hike it in the uphill direction as usually I consider it easier, but in our initial confusion as to where to get into the canyon we ended up hiking it in the downstream direction. Most other hikers we saw there also did it in the same direction as us, but we did encounter a few who were going uphill. In the beginning it was possible to simply squeeze to the walls and let each other pass through, but further down the canyon the narrow places were narrower and more frequent. Encountering other hikers meant looking for a place to step aside momentarily, or getting really really close in order to allow the others to pass.
The Slot

Nearly all the walk through The Slot was easy, and we moved fairly quickly down the path on the fine gravel of the dry wash bed. If it wasn't for the late hour I would have liked to slow down a bit and enjoy more the time inside this pretty canyon. In one place though, we encountered a large boulder that blocked the path. We had to go around it, then descend from the ledge it formed, which was as high as an average person. Some of us jumped down, others lowered themselves slowly to the pot where it felt more comfortable to let go and drop to the bottom. Either way, it didn't slow us down much.

A more serious point of concern (not really) was the narrowest part of The Slot, where we needed to really squeeze ourselves sideways. We all passed through successfully, although the elder chika's camera got dinged a bit from hitting the rock.

Further downstream the canyon became much deeper, and the strip of sky thinned and dimmed. Now it truly felt as if we were walking through a tunnel. I looked warily at a column of rock that split off the south wall of the canyon and leaned precariously on the north wall. I hoped it wouldn't succumb to gravity while we walked underneath it.
The Slot

At home I compared the photos I took on this hike with the photos I took on that same trail 11 years before that. That leaning pillar wasn't there then, it was a newer erosion outcome. On the other hand, a large boulder that was resting above the slot in 2012 has since then found its way down to the canyon bottom. It might have been the very same boulder that blocked our path earlier, or that it had since washed down the canyon, falling apart on its way.
The Slot

Almost without noticing, we passed through the narrow part of the canyon. The Slot has widened. A little at first, then more. We could now walk all of us abreast. The sun was lower now too, but enough light could penetrate the canyon depth and I could see better the intricate erosion patterns on the rock walls. I called my young chika and together we named the figures that came up in our imagination when we looked at these patterns.
Stone people figures marching down the rock wall

The sun was on its way to set but the moon was already high in the sky. At the waxing gibbous phase, the moon was nicely visible against the deep blue of the clear desert sky.

There were no plants in the narrow, slot part of the canyon because of the low illumination and the occasional flash flood that would erode rocks and uproot plants. In the wider part of the canyon had also more room for vegetation.

Plants have established themselves mainly in the quieter, lass flood-affected sides of the canyon, secure between less mobile and prone to tumbling rocks. Some of them were even blooming.
Emory Rock Daisy, Perityle emoryii

I saw there one of my all time favorite desert bushes - the desert holly. It's little red buds looked very pretty against the plant's gray, furry leaves.
Desert Holly, Atriplex hymenelytra

The trail continued near the north side of the canyon for some distance, and followed the curve when the canyon itself turned north. The rock formations of the canyon sides were now less approachable, but no less interesting. Still I saw some nice erosion formations near the trail.
Rock knob

The canyon widened even more, and the lowering sun lit the eastern walls. We picked up our pace figuring there wasn't much daylight left.

When we neared the place where we would exit the canyon the chikas asked fora break. A wide dirt road descended from the west side of the wash and continued north in the wash in the downstream direction, which was north. A few concrete cubes separated the road from the wash upstream of the road - blocking vehicles from entering The Slot part of the wash. These concrete cubes were of perfect size to sit on, so we did.

Pappa Quail and the elder chika didn't stay sitting for long - there were birds hopping in and on the bushes nearby, enjoying the last moments of direct sunlight to reach the wash bed that day.
Rock Wren

These little birds are right at home in the arid desert habitat. Their colors were perfect to blend them in with their surroundings, giving them the camouflage they needed to avoid predators. Except when they make themselves conspicuous, of course.
Brewer's Sparrow

While my family borders were trying to get the best photos of the little desert birds, I enjoyed the colorful sediment layers that were visible in the western wall of the wash. When we hiked this trail 11 years before we were joined by another family whom we met at the Palm Canyon Oasis and made friends with the day before. On that hike one of their kids asked me a riddle - which stones were older: those embedded in the top sediment layer or those in the bottom? I admit I flanked that riddle, saying naively that the bottom stones were older. It is, of course, the opposite, because the top layer was deposited later, therefore the stones embedded in it were dislodged from an older bedrock somewhere upstream,

I returned my attention to the local wildlife, the anthill that my young chika found and asked that I'd photograph for her.
Ants

We watched the sun disappear below the west wall of the wash. It wasn't the official sunset yet but it sure felt like it. We got up and continued toward the dirt road that would lead us up and out of the canyon.


The road west cut straight up the steep hill. It looked pretty steep for vehicles but the road looked like it was being in regular use of OHVs and Pappa Quail said that even our car could do it. I thought to myself that I'd rather not be the one to try this. I sign posted at the bottom of that slope said that this road was one way - people were allowed to drive it downhill only. We weren't about to drive it at all, be were going up on foot.
Uphill Road

All the way up I was worried that a car would come charging down the slope> Thankfully, none did. There were a few plants growing on the slope near the road - mostly plants I've seen earlier on the hike, but some others too.
Indigo Bush, Psorothamnus emoryi

\on the way up I paused a few time to take photos of the view. I feared that by the time I'd reach the height of the ascend the sun will have already set and the pretty illumination would be gone. I remembered the large slab of 'Swiss cheese' rock layering the opposite slope. It looked the same as it did a decade ago.

Surprisingly it was the young chika who reached the top first. This steep uphill part wasn't long but it did get all of us panting.

At the top of the ascent was a small parking area, empty of cars. The place was already under the shade of the evening but the east was still lit with the red evening light. The view was much wider from the top and the large wash that The Slot spilled into was huge.

We started back south on the dirt road and were able to catch the last sunlit patch of the trail. Cholla cacti were glowing in the sunset light, which made each of their thorn very visible.
Rock Horn Cholla, Cylindropuntia acanthocarpa

Beautifully lighted in the sunset were the tall and stringy Ocotillo bushes. Usually at the end of the dry season the Ocotillo are bare of leaves but the past summer brought some monsoon rains and it was lovely to see at least some of the Ocotillo bushes foliaged.
Ocotillo, Fouquieria splendens ssp. splendens

 My family birders found a Say's Phoebe bird and followed it to another Ocotillo bush where it settled comfortably between the plant's thorns.
Say's Phoebe
 
The younger chika called me over to where she was - she had found yet another wildlife. Beetles might not seem as fancy and attractive as birds but they still are an important part of the local fauna.
Beetle

The trail curved a bit, bringing use close to the edge of the cliff. I stepped off the dirt road and went over to look down into The Slot, where we had passed through earlier. It looked empty - no one else was going through in this hour. 
The Slot

I raised my gaze looking over the jagged terrain above the canyon. Once again I admired the way in which the desert shares the sight of the powerful erosion force of once in a long while flash floods.

The young chika waited patiently for me until I finished looking into and over the canyon. I joined her back on the dirt road and we hurried after Pappa Quail and the elder chika, hiking the last leg of the hike under the quickly disappearing post sunset light.


The drive back to the pavement and the town of Anza Borrego we did in the dark. It was a long day and I was glad we got to hike this lovely trail before it ended. On the morrow we planned to hike the very same trail where we had met our friends from 11 years ago - the trail to the Palm Canyon Oasis.
