One Year Ago Today: Some Talus Up Close, a Lake in the Humboldt Sink, and Bonus Fall Colors

It was a fall day, and while driving out to my field site near Winnemucca I stopped for a hike. I got up high enough to see the water in the Humboldt Sink quite clearly (although way off in the distance), and I clambered over piles of talus. The tallish cheatgrass and possibly an ephedra bush are showing their fall colors, though the cheatgrass takes on this straw yellow color by mid June, and keeps showing it until it regenerates itself from seed sometime in the spring.

And here I am, on top of part of the talus, with a great deal of foreshortening going on so the hill seems nearly flat, and the nicely filled but not overflowing Humboldt Sink is in the background. My Jeep can be seen as a vague dot between talus and lake about half way between the center and right of the photo and not far above the vertical center. Water in the desert is always a precious thing, and it's always something worth stopping for.

Somewhat unrelated: I stopped along the Truckee River before making it to that rocky perch above the Humboldt Sink and took a few photos of bright yellow leaves.

From the Road: Fall Color along the West Walker River, CA

We're looking southwest at mountainous terrain along the West Walker River, with what looks like granitic rock—the light-colored rocks in the foreground and on the tree-covered high slopes in the background—and some dark-colored, mafic-looking rocks exposed in the middle-distance ridge that slopes down toward the river from right to left. These mountains, which are on the west side of Highway 395, are technically part of the Sierra Nevada.

Update from the Lake: It's Fall Again!

It's been a slow fall, it seems, and when I went out looking for brightly colored leaves yesterday, I didn't find all that many. One reason is that we've cut down all the aspen trees: they take over the yard and block the sun from our newly planted fruit trees and berry bushes ("newly" being in the last couple years). I did find one aspen that hasn't yet gotten pulled as the weed it is; its leaves (above) were mostly green, showing the lateness of the fall.

I went around and photographed some of the more colorful leaves.

Peach tree leaves.

Same plant; closer view.

Wild plant through rusted deer fencing.

Orange lilac leaves, with a hint of new fencing behind.

Leaf from our Surefire™ pie cherry tree.

Some of these pictures remind me of my leaf series watercolors. Maybe I'll start painting again!

This same cherry was nearly killed by a deer last year.

Leaf from our 4-way apple tree.

Not sure which of the four strains that leaf is from. Most leaves on the tree are still green, and a few went directly to brown. Not sure if more will turn yellow, but we are getting a freeze tomorrow night, so...maybe.

The aronia berry leaves have all turned bright red!

As have some leaves on the holly.

Filbert leaves, only partly turned.

Here's one of our Carolina allspice bushes next to an aspen stump.

Carolina allspice leaves.

And now, I'm back outside, under gray skies, to label plants and continue with roof tear-off cleanup. It's busy around here this fall!

Twelve Months of LFD 2014

I missed this retrospective meme last year (as I also did in 2011), but here it is, back again, per DrugMonkey:

The rules for this blog meme are quite simple.
-Post the link and first sentence from the first blog entry for each month of the past year. I originally did this meme, after seeing similar posted by Janet Stemwedel and John Lynch. Prior editions include 2012, 2011, 2010, 2009 and 2008.

Previous takes on this Twelve Month meme at LFD were posted for 2008, 2009, 2010, and 2012. As usual for LFD, I've also added the accompanying first photo of the month, where there was one with the first post of the month, and a gratuitous sign photo for October.

So, here's the year 2014 for LFD:
January:

I'm sitting here inside flight 112--I think--with my phone in airplane mode, wondering if I can create a blog draft that I can save and post later.

February:

We've been having unsettled to stormy weather here in western Nevada for about the last week, with at least light snow accumulating in the mountains, though the south facing slopes have gone back to being mostly bare, even under today's cloudy skies.

March:

Flying back from Alaska on yet another recent trip, I was able to spot Rose Spit, which featured as Where in the West challenge back in October of 2010.

April:

A while back, I started collecting photos of Majuba Hill (AKA Majuba Mountain), partly because I pass by daily on the way to and from work, and also because of it's interesting shape and fascinating geology (which I hope to learn more about on this spring's GSN field trip).

May:

MOH and I will shortly be off on a field trip to a few nearby localities, including Majuba Hill, reportedly a great mineral and rock collecting site, seen here from I-80 looking northwest across Rye Patch Reservoir.

June:

Here are a few photoviews from Majuba Hill, while I get it together to take some rock photos:

July:

A quick report on a canoe trip we took recently:

August:

So, while I wasn't thinking about it, my 1000th post posted, and this is my 1005th! I'm not sure, really, what to say about this — although I'm also sure I'll think of something — other than Yay!!

September:

The sun is about to rise through thick smoke blanketing the
southern Humboldt Range.

October: A colleague of my former (deceased) husband once said, "Archaeologists are the Cowboys of Science."

[He was wrong, btw. Read the post to find out why.]

November:

So there I was, traveling west on I-80 late last week — just after our first rain sans snow (except for at the high elevations of a few mountains east of the Sierra, like the Humboldt and Sonoma Ranges, which top out at 9836 and 9396 feet respectively), and before our most recent larger rain and snowstorm of this past weekend — when I came to the marshes that border the west end of the Fortymile Desert.

December: MOH turned me on to this song just yesterday (I didn't listen to much besides classic rock and country in the 80s).

More Dust Devils

I often have occasion to see dust devils while traveling through Nevada, especially in the dryer months, but any time of year can afford the right conditions: a dry playa or dirt road (and other surfaces, read more here) and thermally unstable air. And so, while driving through the Fortymile Desert and about to pass by the Nightingale Hot Springs exit on I-80 back in early October —  the exit name combines two locations into one: Nightingale is from an old mining district and ghost town  in the Nightingale Mountains north of the freeway; Hot Springs is from the geothermal area at Brady's Hot Springs just south of the freeway — I noticed a large plume of dust rising from the desert just north of the highway. I pulled off, securing a viewing point near a powerline road crossing the main road going north to Nightingale.

Several dust devils, including the large, obviously whirling one, and a few tiny ones. Photo looks southwest toward basalt covered hills on the east side of the Truckee Range.

The large devil and three small ones apparently trailing it.

The same large dust devil, this time with two tiny ones seemingly leading.

Here, the same large dust devil appears to get all torqued out of shape!

Later, just for good measure, I took a photo of this devil, also in the Fortymile Desert; our view is southward toward the West Humboldt Range.

This last devil was located about 14 or 15 miles east of the group near the Nightingale Hot Springs exit. The white, rectangular thing on the horizon in the left part of the photo is a semi heading north on U.S. 95, about to reach I-80 near the old site of Trinity (MSRMaps location; Google Maps location).

Sluggish Fly on A Pyritic Boulder

It's not like it's a meme or anything, but I saw a sluggish fly on limestone at Really Going Places — after taking these photos on the first day of November — and thought, what an opportune time to post photos of this fly, also sluggish, on a pyritic parking lot erratic (glacial erratic? not sure).

Iron-stained rock with a large mass of pyrite in the upper right, with fly for scale
(a bit left of the large pyritic mass)..

The same mass with the fly close to a large pyrite cube.

Now the fly has wandered over a bit to the left (out of the first photo's range), and is standing at a small precipice, appearing to check out the tiny pyrite cubes below.

Here, I've had to give the fly a gentle nudge, because I wanted it to move closer to the tiny pyrite crystals (that's how sluggish it was!).

The fly now looks like it's interested in mining the tiny cubes!

And now the fly has moved over a bit back to the right (barely into the first photo), and is checking out a couple veinlets.

And here's one last photo, for those of you who prefer not to see a fly for scale.

The funny, almost sickly yellowish green color on the outside of this rock indicates that you should be able to find some kind of sulfide mineral inside — in this case, a heckuva lot of pyrite. This color can be used as an exploration guide, provided that one wants to find an ore deposit rich in sulfides.

Update from the Road: It's Finally Fall

So there I was, traveling west on I-80 late last week — just after our first rain sans snow (except for at the high elevations of a few mountains east of the Sierra, like the Humboldt and Sonoma Ranges, which top out at 9836 and 9396 feet respectively), and before our most recent larger rain and snowstorm of this past weekend — when I came to the marshes that border the west end of the Fortymile Desert.

One of the marshes bordering the west end of the Fortymile Desert,
just northeast of Fernley (location).

I was pleased to see that the marshes were fairly rich in water, and that even the median between the eastbound and westbound sections of freeway had patches of water. The volume of water in the marshes, in the median, and in the adjoining playa and Fernley Wildlife Management Area varies considerably, and though the area has been somewhat drier than usual this last year, I've never seen the marshes completely dry. I enjoy driving this section of I-80: I often see birds in the marshes, including American avocet and black-necked stilt.

I passed through Fernley, stopping briefly at the Gilpin rest stop (AKA Wasdworth rest area), always a good place to find excellent fall colors.

Trees at Gilpin.

And a closer, brighter view.

I had already crossed the main bridge over the Truckee River, between the west Fernley and west Wadsworth exits, and I had been surprised to see that the trees along the river were still yellow. They had been, I thought, nearly at peak about two weeks prior, so I really didn't expect to be seeing much besides some faded golden brown leaves or maybe even mostly barren trees.

Instead, fall was in full swing, and I was reminded that the same was true just almost exactly a year ago when I passed through and decided to exit at Painted Rock to get a closer view of the leaves.

The river and colorful trees, from the one lane Painted Rock bridge (location).

This year, I didn't exit anywhere along the river (besides Gilpin/Wadsworth), opting instead to move through the canyon as quickly as possible (such are the vagaries of a traveling life).

After driving into Reno, I navigated the notorious Spaghetti Bowl, turning north onto 395. Eventually I stopped at the Honey Lake rest area.

The changing leaves and general fallishness of the marshes reminded me of a detailed sequence of events from last year — of the bright golden leaves turning and falling in the canyon of the lower Truckee River, of other leaves turning and falling elsewhere along the road, and of the bright yellow aspen leaves in our yard, also turning and falling. We don't have aspen trees in our yard anymore (we had to make space for gardens and trees that don't perpetuate themselves through annoying, ever-present and ever-growing roots and sprouts), so we don't have our own bright colors and fallen leaves (except for on a few small plants in the midst of growing), but I know that fall will always come about this same time every year — often with bright colors — and possibly I will always feel nostalgic for the days gone by.

Cliffs of the Ruby Mountains: Mt. Gilbert

The glacially carved cliffs around Camp Lamoille are truly spectacular — and while we were, now nearly a month ago — they provided us with constant fascination and wonderment amid the ever-changing light and cloud effects. To the south of us, besides Ruby Spire and the Wolf's Ear (seen in this earlier post), Mt. Gilbert towered over us at 11,120 feet.

A view of Mt. Gilbert, the highest point near an unnamed spire, as seen on the second day from the trail near the South Fork beaver ponds.

A closer view of Mt. Gilbert and the same spire;
photo taken on the second day from the main part of camp.

In the view above, you can see a couple spots of snow high on the cliffy slopes, probably left over from the previous winter (2013-2014).

Mt. Gilbert is a pyramid-shaped peak, possibly qualifying as a glacial horn, AKA pyramidal peak (British usage?). As you can see below, it's bounded on the west by the large bowl-shaped head of the glacially carved, U-shaped Seitz Canyon; it's bounded on the northeast by a high, well-defined cirque; and it's bounded on the southeast by an irregularly bowl-shaped area, also a cirque.

Topo map from USGS TNM 2.0 Viewer (link), with Mt. Gilbert right of center.

Same map, with the outlines of three circular depressions or bowls formed by glaciers. As you can see, the west side of Mt. Gilbert is essentially one arête. Other horns and arêtes are present in the topo image.

It just occurred to me that the unnamed spire might also be a small horn, but only if the indentation into the cliff below it to the east consists of a small cirque formed from a small hanging glacier (I wish the USGS would provide individual links in their Glossary of Glacial Terminology, but they don't).

What do you think? Is it a horn?

Rain and hail from an intense, long-lasting embedded thunderstorm (or set of storms), pounded the Lamoille Canyon area late on the second afternoon and long into the second night. When we awoke the morning of the third day, the tops of the cliffs and peaks around us were well dusted with snow:

A closer view from the same time, same location. The snow highlights the foliation of the metamorphic rocks — gneiss and marble,
possibly with sill-like intrusions of granite.
