Date: December 28, 2020
Place:Valley of Fire State Park, Las Vegas, Nevada

Length: 0.9 miles
Level: easy
 

The original destination we planned for the the winter break of 2020 was closed down due to the pandemic so we changed plans and went to Las Vegas to have our family vacation there. Not once did we visit The Strip or any casino - we focused on nature only. by the third day of our trip we have hiked at the Petroglyphs at Sloan Canyon, the Clark County Birding Center and part of Red Rock Canyon National Conservation Area. Now we headed a bit further northeast to explore the famed Valley of Fire State Park. 
Right off the bat, a short distance into the park we pulled over into a road side parking area and joined the few other cars that were parked there. The attraction that attracted us from the main park road was a herd of bighorn sheep.  These sheep were very docile and seemed to be completely non-phased by human presence nearby, allowing is plenty of time to observe them and take photos. This was unprecedented - all other times we've seen the bighorn sheep, as in Carrizo Canyon or in Death Valley, they were very hard to find and when we did find them they were skittish and kept a distant.

It was hard to detach ourselves from the sheep but eventually we did go over to the visitor center which was, to our surprise, open to the pubic. Inside the visitor center we received information about the park and outside the building we had some more encounters with the local wildlife, especially the feathered type. 
Cactus Wren

Quail are always fun to see. In that part of the country there are no California Quail, but the beautiful Gambel's Quail that are very similar in both colors and behavior.

Phainopepla is perhaps the signature bird of the southwest desert, even if it wasn't made famous by a cartoon as the roadrunner (which we didn't get to see that day).

At the visitor center we received recommendation for hikes for that day, and shortly after we were parked at the trailhead of the first hike - that of the Mouse's Tank Trail.

The main attraction of the Mouse Tank Trail were the petroglyphs, we were told at the visitor center. We haven't seen a single petroglyph yet and I was already awe-struck by the beauty of the place's geology. 
At the Trailhead

The rocks here were of red sandstone and the erosion created beautiful patters. The trail was made of fine, red sand. There were other hikers on the trail but it wasn't too crowded. 

The trail delved into a canyon. The wider parts of the canyon had quite a bit of vegetation growing there, most of it seemed dry. Of the plants that did look thriving were a number of large cholla cacti. 
Cholla, Cylindropuntia sp. 

About a third of a mile into the hike we came upon the first petroglyph wall, but the first thing that caught my eye wasn't the human-made artifact but an interesting rock shape. 

Under certain conditions rocks in arid areas develop what is called, "desert patina" which is a thin dark layer of oxidation - a rust, in a sense. Scratching that surface leaves a contrasting mark, and that is exactly what the ancient people of the desert did when they inscribed the petroglyphs in the rock. 

The rock walls of of the petroglyph canyon along the Mouse's Tank Trail are some of the most dense canvases for petroglyphs I've ever seen, both in numbers and in variety of figures and shapes. Many of the figures were easily recognizable as human or animal shapes. Many more figures were completely abstract to me, and I couldn't even imagine what they might have meant to the people who created them. 

The large petroglyph walls were an attractive backdrop for people to take their photos with. In two occasions (not that in the photo below) I've seen kids climbing these rocks with their parents cheering them on, which I though in the best case was a bit of a bad taste and in the worse case, could be destructive to the ancient artifacts. 

The Valley of Fire is in the high desert and it does get pretty cold in the winter. It was a cold and windy day when we were there, and clouds raced fast high above. No rain was anticipated that day, but we were bundled up for the chill. 

Among the plants that I've seen growing in the wash were some rabbitbrush bushes that were in full bloom, as if we were not heading into deep winter. It was lovely to see the unexpected flowers.

The next petroglyph wall was high above the wash bed and it was more difficult to see the inscriptions in the rock face. 
Giant Petroglyphs Wall

The strongest zoom setting of my lens revealed some interesting figures such as the hand prints petroglyphs. The patina of the wall seemed to have peeled off much of the rock face, an erosion that probably eliminated many petroglyphs and had rendered many others much harder to detect because the contrast was gone.

Even without the petroglyphs, these rock shapes were interesting and inspiring to the imagination. The one in the photo below reminded me of a pirate skull. 

Deeper into the canyon were more petroglyphs, and they were closer to the wash bed and easier to see. I assume that at the time these were created, the wash bed was higher. Otherwise inscribing them would have been a very risky business. 

Bighorn sheep were a regular theme in these petroglyphs. They were probably a staple of the local people in ancient times. 

For the most part the trail was comfortable enough to simply walk on, but there were places where we needed to hop on some rock face. Nothing too challenging though. 

More and more petroglyphs appeared before us the deeper we got into the canyon. The richness of these markings was simply staggering. 

I took a huge number of photos on that hike, most of them of petroglyphs. Choosing which to post here was probably the most challenging part of the this hike's accounts. I had to include the ladder and the pronghorn image, of course. 

Many of the rocks and the eroded slopes of the canyon looked like they would be fun to climb. The chikas did indeed climb a bit, bit not very high and not for too long. I resisted my urges and stayed below, on the trail. 

The clouds were beginning to recede but for the most part we remained shaded from direct sunlight. We did warm up enough to begin peeling off some layers. 

The canyon opened up a bit and on the side was a hill that looked holed with many little caves. The caves looked natural and way too small to house people but I presume that animals to find shelter in them when needed. 

I took a closeup photo of one of the lower holes. This one did look like people may have blocked the entrance with large stones, but I suspect this is recent work, possibly done by the park authorities to stop visitors from going inside.

We kept moving on down the canyon. We were in fact, going downstream the wash, with the flow of the creak when it flows. 

More petroglyphs appeared before us. One of them pictured, very clearly, a hunting scene. In good timing the sun appeared from behind the cloud to shine on the ancient art. 

Next to the hunting scene was a petroglyph that looked to me like a barrel cactus, and to its left some marks that could have been a saguaro with some birds flying around it. 

Off to the side was a lone human figure engraved in the rock. It wasn't more special than the other human figures we've seen but he looked very lonely there. 

A face looked at me from the rock - not a human made one, but a natural rock formation. It looked like a sad baby elephant. 

Meanwhile the sun was winning the battle over sky space, and the canyon lit up as the clouds split and moved away. 

Rock spires were another prominent feature on the sides of the canyon, each with its own shape and character. 

In some places I found erosion holes in their early formation stages, with circular markings just like I saw in the Calico Hills of the Red Rock Canyon NCA. 

The canyon curved north and at that spot another tributary wash joined in from the south. The trail continued north and entered a very narrow part of the canyon. We had to squeeze ourselves sideways to go through. We were getting very close to the end of the trail. 

At the end of the trail was another large petroglyph wall, but what attracted my attention first was a lovely, lush mesquite bush that was growing near it. 

The petroglyphs wall at the end of the trail wasn't was impressive as those we've seen earlier on the trail. We looked at it for a while but we spent more time sitting for a bit of a snack break. It was the point of turning around and walking back. 

Walking back up the trail was much faster. We didn't stop anymore at the petroglyph walls or the rock formation - both Pappa Quail and I wanted to squeeze as much as we could into this one day that we allocated for the Valley of Fire, and we didn't want to delay. 

It was very nice though, to see the rock spires now fully lit with direct sunlight. This really brought up the lovely red color of the rocks. 

Cushions of brittlebush, another one of my favorite desert plants, adorned the rock mounds by the trail side. The brittlebush was past its bloom season and the dry inflorescence stems surrounded the main bush body like a spiky yellow halo. 

The canyon opened up and widened - we were getting close to the trailhead and the hills on the other side were already visible. 

Like the petroglyphs, I photographed also many rock formations. Here too I had a difficult time choosing which to include in this hike's accounts. One last formation for this blogpost is the rock arch I saw high above the trail. On a different time I might have climbed there - it didn't look difficult and there were plenty of evidence that other people have climbed there before. As it was, I simply admired it from below, then run ahead to follow the rest of my family which were already at the trailhead. 

At the trailhead I turned around and took in the view of the hills above the plateau near the trail. The broad scenery was breathtaking. 

The ancient people that lived in this desert were very artistically prolific. Like the petroglyphs of Sloan Canyon, those that we saw in the Valley of Fire were many, and very rich in imagery. There is no direct historical link to the people who made these petroglyphs, and we can only guess what they meant and what were the reasons for inscribing them. I am happy to have seen these though, and I hope that they will be preserved for many more years to come.

Late Summer Redwoods: Hiking at Sam McDonald County Park



Date: August 20, 2024
Place: Sam McDonald County Park, La Honda, California
Coordinates: 37.296606, -122.265540
Length: 6.1 miles
Level: moderate


It is normal for me to hike at a slow pace, unless of course, I am in a hurry. In the last year however, my slow pace resulted also from advanced arthritis in my left hip which caused me great inconvenience and considerable pain. The situation deteriorated to the point that nothing else worked anymore and I scheduled a hip replacement surgery for the end of August. Knowing I'd have a long period of home rest without any hiking I was eager to get one more trail hiked before the surgery. So three days before I was planned to get under the knife I connected with my friend and we met at Sam McDonald County Park for a hike in the redwoods. 
The first thing I saw when I stepped out of the car was a single banana slug that was half hidden under the log marking the edge of the parking area. 
Banana Slug

The visitor center cabin was closed. My friend an I paid the parking fee using the little envelopes they had there, grabbed our packs and started down the path that led to the trail of our choice.

 A short path connects the parking lot to the road accessing the park. The trailhead we sought was on the other side of that road. Right by the connecting path grew an old redwood tree that had a through huge fire cavity that ran along most of its trunk length. I just had to look through it. 

The trail we started on was the Towne Fire Road which, as it was named, was a wide dirt road. It was convenient to walk on, but its slope was pretty steep at times. We started hiking uphill right from the trailhead, going at the slow pace that my condition allowed and enjoying a friendly chat and the grand view of the redwood trees.
Towne Fire Road

It didn't take very long before I stopped short and stepped off the trail - I saw an orchid in bloom! I already knew this orchid species - it was not a California native but an introduced species. Still, an orchid is an orchid. Naturally, I spent some time taking its photos from every direction. I later saw many more of these orchids on this hike and my excitement subsided a bit, but I still took more photos. 
Broad-leaved Helleborine, Epipactis helleborine, non-native

Other things that thrill me are pretty spider webs. I see these utilitarian webbings as nature's works of art. In this case, the artist was sitting right in the middle of its creation.  

We saw many spider webs on that hike, most of them of the dome web type, but this one was different - it weaved a tunnel, a hiding place for itself, at the top of its web. 

We came upon a side loop trail named, "Big Tree" and we turned onto it, hoping to see an old growth redwood there. 
Big Tree Loop Trail

There might have been an old growth redwood there indeed but my friend and I were in the midst of a heated debate so it is likely we simple stormed by the tree without noticing it at all. When We came back to Towne Fire Road a bit further up I remembered about the redwoods, and although I didn't turn back, I did photograph the high canopies of the nearby trees. 
Coast Redwood, Sequoia sempervirens

Once again on the wide dirt road that was Towne Fire Road Trail we continued uphill, but the slope was milder now, and even dipped a bit at times. By and by we started seeing other hikers as well. 
Towne Fire Road

A thick redwood forest doesn't let much sunshine through, so the forest undergrowth plants aevolved for high shade tolerance. I was glad seeing them down below the trees. Some of them were even blooming still. 
Foamflower, Tiarella trifoliata

Other forest floor plants were already in their fruit stage. There are a few species of False Lily of the Valley plants on the redwoods of San Mateo County, but based on the fruit and foliage alone I couldn't determine which species was the one that I saw there. 
False Lily of the Valley, Maianthemum sp. 

Towne Fire Road Trail had a lot of trail junctions leading to other side trails and zig-zag turns. At each such intersection we needed to make sure that we were on the right path, going in the right direction. 
Towne Fire Road

As we approached the next curve I saw a covey of quail up the trail and immediately pulled my friend to the side. I pointed them out to her, and commenced taking photos. I took many photos of that covey, as they run on the trail, and I'm embarrassed to admit that none of them turned out very good. I blame that on the distance of the birds, on of course on the forest's treacherous lighting. The quail were very cute and fun to watch, but eventually they vanished in the forest and we resumed our hike. 
California Quail

It didn't take long before we had our next wildlife excitement in the shape of a beautiful young buck that we spotted across the creek from us, walking at ease on that steep mountain slope. The buck noticed our presence and stopped, ;looking at us gravely for a long minute before moving on. 
Black-tailed Deer, buck

We were about to move on as well when we noticed another deer - a young doe that was following the buck. The doe paused in exactly the same place that the buck did, looking at us as well. Eventually she moved on too and my friend and I continued up the trail. 
Black-tailed Deer, doe

We reached the high part of the park. Towne Fire Road was going all the way to the junction with the Heritage Grove Trail which we planned to take back downhill, but when I saw that there was a hikers trail that paralleled the dirt road I pulled my friend to walk on that one instead. 
East Brook Trail

We didn't see many birds on this hike. We heard them - they were in the trees, but they didn't make themselves visible. I was happy therefore, too see a single towhee perched on a low redwood branch right by our trail. Looking closer I was less happy for the poor bird - he looked unhealthy. I hope that he made it through whatever that was. 
California Towhee

Up on this path we got our first sight of an open area - a true forest clearing with savanna like grassy area that was bathed in sunshine. 

Nearing the end of August, the grass was dry and yellow. There were some green plants here and there in the open field, and some of them where blooming still. 
Aster

For a short distance we merged wit the Towne Fire Road again. By then  the debate my friend and I had moved from politics to dentistry. I'm not sure why I remember this particular detail, it must have been painful enough. 
Towne Fire Road

The California coast is one of those regions where some wildflowers can always be seen, year round, even if very few. As the end of summer was drawing near and most plants have gone to seeds already, I was still finding some wildflowers at the driest part of the hike. 
Varried-leaved Collomia, Collomia heterophylla

Not all the wildflowers I saw were native species of California. I don't usually post photos of invasive species in my blog but sometimes their beauty overcomes my resistance. In the case of the thistle in the photo below, it was the lighting that gave it the glow. 

Shrubs and vines can afford themselves a longer bloom season than annual herbaceous plants. I was happy to see some honeysuckle also blooming by the trail. 
Pink Honeysuckle, Lonicera hispidula 

My friend was not as interested as me in all the local flora but she patiently put up with my enthusiasm and with me pointing out and naming out loud all the wildflowers we've seen along the hike. This has never stopped her from joining me on the trails. 
Spanish Lotus, Acmosipon americanus

For a brief distance the view opened up before us and we could look ahead onto the rolling slopes of the peninsula ridge mountains and a lovely endless-seeming conifer forest. 

Although the forest here was primarily of coast redwood, other conifer species were also quite prevalent. One of the more common trees in the surrounding forest was the Doulas fir which can grow almost as tall as the redwood. 
Douglas Fir, Pseudotsuga menziesii

We reached Heritage Grove Trail junction and start on the trail that would take us down the mountain. We wanted to take a break but didn't want to sit in the sun so we kept going on, hoping that a suitable location would present itself soon.
Heritage Grove Trail

The last dry clearing we crossed provided the nicest wildflower species I've seen on the hike - the California fuchsia. The bush had only a few flowers still open but it was lovely to see. 
California Fuchsia, Epilobium canum

Soon we reentered the forest and started walking downhill. After some distance in which we couldn't find a good place to sit we simply stopped in a place that was a bit more wide and clear and sat down for a short snack and water break. 
Heritage Grove Trail

My friend was pressed on time so we didn't sit for very long. Now we were in the forest once more, but on this side of the slope, there were also oak and laurel trees mixed in with the conifers.. There were also other species of wildflowers blooming along the path. 
Hedgenettle, Stachys ajugoides

It also seemed to be a wetter slope of the mountain, with a deeper canyon and a creek that may have run water until later in the season. There were many more ferns growing on the slopes above and below the trail, and they looked lush and healthy. 
Five-fingers Fern, Adiantum aleuticum

For the most part, the Heritage Grove Trail was a narrow hiker's path. The trail's name inticated the presence of old growth trees but we didn't see any. All the redwoods along the trail were younger growth, sprouted after the big logging that devastated the area in the late 1880s. 
Heritage Grove Trail

We did see plenty of the old growth stumps all along the trail. They were a sad reminder of the devastation that human greed can inflict on nature, often with consequences that directly affect the next generation of resident people. Redwood trees however, are exceptionally resilient, and nearly all the renewed forest are of trees that are clonal to the downed old growth, having sprouted from the same root crown. 

Redwood trees also fall on their own, and we saw plenty of fallen logs forming natural bridges across the creeks we crossed.
Heritage Grove Trail

A large area of the redwood forest floor was covered with redwood sorrel - one of the herbaceous plants that evolved to thrive in the deep shade of the forest. The redwood sorrel, a relative of the sour grass, has very pretty flowers, but I didn't expect to see any so late in the season. To my surprise, we did come upon a small patch that had a couple of open flowers. 
Redwood Sorrel, Oxalis oregana

 Nearby was a snowberry bush, but its beauty was in the snow-white berries. We were hiking there at exactly the right time to see those lovely ghost-like berries. 
Snowberry, Symphoricarpos albus

Down and down and down we walked, at a fairly quick pace. Eventually we reached a trail junction with a wider dirt road. It was there that I made a mistake and instead of taking the right turn that would have taken us directly down to the road, I pointed to the left turn and my trusting friend followed me there on a needless extension of more than half a mile, half of it on a steep incline. That steep connector placed us right back on Towne Fire Road a bit higher from the Big Tree Loop. It was only there that I realized the mistake I made. My friend wasn't happy about the time wasted, but the only thing we could do now was to point ourselves downhill and gallop down as fast as we could. 
Towny Fire Road Trail

We reached the road and crossed it to the trail connector, where I did take a moment to photograph again the large redwood with the huge crack cavity in the middle. 
Coast Redwood, Sequoia sempervirens

Three days after this hike I went into the surgery room. I've resumed hiking since, but I have not yet gone back to the redwoods. Sam McDonald County Park has a very nice trail system and some adjacent forest open space to explore. I loved the trail of this hike and I hope to get over there again soon.
