Mojave Desert: December 2020

 We wanted a brief socially-distant trip so that we could watch the Geminid meteor shower.  Solution:  the Mojave Desert, just 200 miles away.  Although all of the campgrounds and state parks were closed, the BLM still allowed boondocking in certain areas, including the Kelso Dunes.

I was concerned that the sites would be too sandy for the trailer, but the surface was great -- no problem.  It was a surprisingly chilly afternoon:

Those are the Providence Mountains behind me.  If you look carefully, you can see that the rock is metamorphic, rather than igneous, which is unusual in this general area:

After we got the campsite set up, we took a long walk.  The dunes were very dramatic in the slanting late afternoon December sunlight.  This shot can't quite capture the silence, the emptiness, and the cold wind:

As we walked, we could see a number of places where folks in those monster trucks had left the road and had ridden right over the "no motor vehicles" signs posted all along the roadway, tearing up the soil and killing the vegetation.  It wouldn't surprise me if someday soon, the BLM were to completely ban boondocking, in an effort to preserve the desert, even though the culprits are probably not campers but are just "day-use vandals."  (Good name for a rock band!)  

This is another in a series of "little trailer in a big landscape" pictures -- the trailer (the lonely white dot in the right center) was reflecting the last rays of the sun:

That evening, just after dark, some rude late-comers drove over the bushes and wedged their truck right next to our trailer, even though the site was clearly meant for just one rig.  (Fortunately, they were very quiet and left the next morning.)

The weather prediction for the meteor shower was for cloudy skies during the evening with clear skies after midnight.  Wrong.  It got very cloudy but did not clear till the next morning.  We saw a few dim meteors when we went out for our after-dinner walk, but nothing spectacular.  The cloud cover reflected a surprising amount of light pollution from Las Vegas, a hundred miles away. (We have become spoiled by the ultra-dark skies in the Eastern Sierra.). There was also light pollution to our west -- maybe Barstow?

December 14:  Since I was about seven or eight years old (during the Eisenhower Administration!), I have always wanted to explore a volcano and to climb down into the crater.  Amboy Crater was less than an hour's drive from our campsite -- a perfect opportunity to scratch that itch.

Kelbaker Road, our route to Amboy, took us past the Granite Mountains.  These were unusual -- most of the mountains in the Mojave appear to be volcanic, but these had that "intrusive batholith" quality common to the Sierra, far to the northwest.  (Translation:  blobs of molten rock that had risen from deep in the earth.)  The outcroppings had eroded into bizarre shapes:

Amboy Crater was about a mile and a half from the parking area.  Felice is standing on a lava flow.  From this perspective, the northern edge of the cone looks symmetrical (unlike the southwestern side):

The volcano had thrown out blobs of lava -- the gases within the lava had created bubbles, preserved as the molten rock cooled:

The trail to the crater snaked through mounds of ejecta and lobes of lava flows.   There were a number of big circular depressions in the lava field -- we could not figure out what those were, because they did not look like little volcanic craters or vents. (No sidewalls!)  A little research indicates that these are "collapse depressions," in which thin crusts over fluid lava collapsed, leaving a void in the flow. 

The hike was not difficult at all, especially since the weather was so chilly.  It would be very tough in the heat of summer.  The climb up to the edge of the crater itself was not too bad -- a little steep, a little slippery.

In this shot, I am standing in the crease on the southwest side of the mountain, where the volcano had erupted sideways (like Mt. St. Helens, only much smaller).  The crater had erupted several times, leaving superimposed lava fields:  

If you look carefully in the center of this next shot, I am in the middle of the crater -- we had it all to ourselves.  The floor of the crater was a lava lake.  Some sand and clay had blown into the crater and had gotten trapped there, leaving a smooth surface:

The nearby town of Amboy was sort of a living museum of the pre-interstate days of Route 66, complete with late 40s/early 50s architecture:

That night was beautifully clear (and cold -- about 30 degrees).  Dressed in heavy clothing and draped in a sleeping bag, we sat outside for about 45 minutes, hoping for some leftover meteors.  The stars were excellent, and there were a few faint meteors, but nothing amazing.

December 15:  We walked up into the Kelso Dunes.  The sand was like flour -- very loose and powdery.  As you'd expect, we would take a step and would slide back a half step.  It was a lot of effort, but fortunately it was another chilly, sunny day.

Felice used her iPhone to capture the wind-driven ripples in the dunes.  The pattern was accentuated by the contrasting sand particles -- the high part of each undulation trapped the darker particles, while the depressions between the ripples were composed of light beige sand.  We could not figure out how the wind had sorted the sand in this way -- perhaps the black particles were lighter or heavier than the beige grains: 

Given the harsh conditions, it was surprising to see that there were some fairly big plants growing out of the soft sand.  (I tried to figure out what this was but have had no luck.)  I read that the larger plants growing on the dunes put out long, deep roots that reach the water table within the dunes, far below the surface:

The grasses were whipped back and forth by the shifting wind, creating some great patterns in the sand:

Although we got close to the top of the dunes, we decided not to go all the way to the top -- the view from partway up was pretty spectacular:

From our vantage point, we could see the trailer in the desert below -- yet another "lonely trailer" shot.  It's in the upper left corner:

Later that afternoon, we headed over to a boulder field near Granite Pass, just to do a little exploring:

Kings Canyon/Sequoia: November 2020

We needed a camping trip – – but a combination of smoky skies and the pandemic had kept us locked up at home.  As soon as the smoke abated, we decided to take a short risk-averse trip to a "comfort food" location, both familiar and close to home:  the Sequoias.

Nov. 16:  The drive to Azalea Campground took us about 6 1/2 hours, and we were able to snag a nice unreserved campsite that was somewhat isolated from the rest of the campground.  (All of the usual Western Sierra boondocking areas in the national forest were behind gates that had been locked for the winter, so we had to stay in a campground.)  It had snowed a little bit a few days before we arrived:

After getting the campsite set up, we took a pleasant walk around Grant Grove in the late afternoon.  Check out the unusual shadowing on the trunk of the General Grant tree -- the light of the setting sun was virtually horizontal:

(By the way, Felice took that picture with her iPhone!)

The very last rays of the sun caught the top of this giant – – the distinctive "broccoli" structure of the crown is clearly visible:

Nov. 17:  Since it was a cold, cloudy day (excellent hiking weather), we took a "forest" hike to Muir Grove, rather than a "view" hike.  We saw one other person on the trail that day, and we had the entire grove to ourselves for more than two hours.  Felice greeted the Sentinel Tree at the entrance to the grove.  (It doesn't actually have a name, but it should.)

There is no way to capture the entire Circle of Giants, but this shot comes close.  (And no, that is not an official name, either.)

Felice noticed that this "goose pen" (an open area at the base of the tree) looked like a heart:

(And those were called "goose pens" because the early settlers supposedly kept geese in there.)

We then trekked off-trail to visit the Husband & Wife Trees (no, not an official name), as we almost always do.  (Felice named those trees because they share a foundation but stand on their own as individuals.)

This is as close to climbing as I get -- which is not very close:

Nov. 18:  Rain!  Not much, but still very welcome.  As is often the case, a cold dark rainy night meant that we slept very late -- till 8 am!  (Full disclosure -- we slept later than we usually do all week.  The temperature inside the trailer at night was in the low 40s:  perfect!  Better yet, the outside temp never fell below freezing, so we didn't have to worry about the water lines.)

After our usual leisurely breakfast, we were off to Redwood Canyon, with our ponchos draped over our backpacks:

The needles of the Sequoia seedlings were tipped with raindrops -- Felice took this with her iPhone:

Although we've been to this canyon many times, we had never before heard the tremendous crash of huge limbs falling from hundreds of feet in the air.  This time, during a few hours in the canyon, we heard four separate limb-drops, not too far away from us.  

It sounded something like thunder:  a sudden sharp crack, followed by a series of rolling impacts as the thick falling branches slammed down and down through the forest canopy, breaking off the branches below, culminating with an earthshaking thud and a final sprinkle of leaves and bark.  Each event lasted several seconds.  Terrifying, but really cool.

It could be that the sound carried so well on this wet day because there was no breeze at all.  Also, there was no air traffic, due to Covid.  The silence was very deep, except for the light rain and the four booming "widowmakers." 

As usual, we were The Only Car in the Parking Lot, which could be a good title for a book about remote day hikes:

Before heading back to the trailer, we decided to explore the road that runs down the mountain from Redwood Canyon to Eshom Campground, something we have long intended to do.  After a couple of miles, here's the bottom line:  too rough and rutted, with very deep potholes and big rocks.

Our high-clearance Tacoma 4X4 could handle the obstacles easily, despite the thick mud.  But it was punishing to be thrown from side to side of the passenger compartment, even at five miles an hour.  That itch has been scratched -- that road is a no-go for us.

On the way back to the campground, we stopped at an overlook.  The rainstorm was clearing, and the rounded crowns of the Sequoias on Sugar Bowl Mountain were poking up through the fog into the late afternoon sunlight:

Nov. 19:  A crisp, clear day:  Little Baldy, of course!  The trail was icy, but our microspikes did the trick.  Note the heavy black canvas snow gaiters -- they kept the snow out of our boots, and they were stout enough to ward off the thorn bushes:

We passed through the "nursery," in which hundreds of seedlings are racing toward the sunlight.  Every year, this patch of little trees gets noticeably taller -- not too long ago, they were knee-high:

As we approached the summit, Felice noticed that someone had propped up a heart-shaped rock:

The dome was much quieter than it usually is -- no wind, no air traffic, no one else for miles around us.  The clouds were well below the summit, leaving the Great Western Divide sharp and clear:

On our way back to the trailer late that afternoon, we came upon a very small bear cub, maybe six months old, sitting in the middle of the road near Wilsonia.  He scampered off before we could take a photo.  But he looked exactly like a high-quality Teddy Bear, plump and fluffy.

Nov. 20:  Another cloudy day, perfect for Giant Forest.  We parked north of the Sherman Tree and then wandered off-trail along the headwaters of Sherman Creek, toward the Wolverton area.  Although the trees were not ancient (maybe "only" 500 years old?), the groves appeared to be very dense and healthy.

This is one of those "Where's Waldo?" shots.  Hint -- I'm in the bottom center of the picture:

Felice's red jacket makes it much easier to spot her:

This was taken with our radio camera trigger -- we wanted to test its range:

 Nov. 21:  The drive home was uneventful.  The trip was a success:  not an epic adventure, but a fun (and safe) escape from the strictures of the Covid era.  It was liberating to come back to an area we had visited so many times before:  we were not under any self-imposed pressure to see all of the sights, racing against time.  We just took our time and relaxed.
