Update from the Lake: Wintry Days

During the recent holidays, I was fortunate enough to spend a few days at my favorite northern CA lake. I was unfortunate enough to be "mildly" ill during that time, recovering from an unknown malady that caused upper and lower respiratory distress, inflammation, infection—whatever—something that the local clinic (in my northern NV home area) did not bother to test for, but gave me two anti-inflammatory medicines, Z-pak and prednisone (Z-pak is primarily an anti-biotic, but who knows if I needed one).
While recovering, mostly by relaxing in front of a wood cook stove, I took a few walks down to the local beach area, where spring water enters the lake.
So, let's go for a walk or two.
Christmas day, it was sunny but occasionally foggy.
The lake has a little picnic area, though it was a little cold for just sitting around.
Nice lake view, looking south toward the dam, which is not in view.
A few days later, I made another hike down to the lake. It was a gray, cloudy day. A bright white line on the shore across the lake stood out, creating a little bit of lighting drama.
Down on the rocky shore, water from a spring feeds into the lake, causing a bit of green—probably algae.
A few old stumps from when trees were cut before the reservoir was filled, back in 1914, are scattered about. Most of the present-day lake bottom consisted of meadow and marshland before filling, so tree stumps exist only along some shores.
The last photo looks west, down the rocky shoreline. Rocks consist primarily of rounded and partly rounded basalt cobbles and boulders, derived from the dominant bedrock of the area: basalt not far below the soil of the surrounding forest. Snow line here is below the high water mark, which is probably about 5 feet below the lowest pine tree, just below the upper concrete slab (concrete?). That is, when the lake is full, you can walk along the shore by moving from boulder to boulder, to do a little fishing (although technically, any land above the high water mark outside the beach area is private land).

The northern section of Highway 8A

Signs at the turn-off from westbound 140 to SRs 8A and 34A
Well, I finally did it! I traveled the northern section of Nevada S.R. 8A, which runs from the NV-CA stateline east of Cedarville, CA, to Nevada S.R. 140, the Winnemucca-to-the-Sea Highway. I posted earlier about the west end of northern 8A here, here, and here. The northeast end of northern 8A was covered briefly in this post, which is part of a series about Highway 140. The traverse described in this post was part of a larger loop trip from northern Nevada to northern California, the westbound portion of which is shown in this map (also embedded at the bottom).
Take the left fork to stay on 8A, or the right fork for 34A.
Looking southeast across Echo Creek at Gooch Table.
Volcanic tableland in the foreground. The Pine Forest Range is on the right; the Pueblo Mountains near Denio are on the left.
The sky was overcast for much of the trip, so the photos I got were not as good as they might have been on a bright summer day. Wildflowers were out—not a superbloom but quite persistent and with numerous species—and I saw three pronghorn in the west-central part of the Sheldon National Wildlife Refuge.
One pronghorn barely visible. The south end of Gooch Table is to the left; the hills beyond the pronghorn are northern slopes off Fish Creek Mountain.
As the northern slopes of Fish Creek Mountain came into view, the area started looking familiar, and I wondered if I'd bushwhacked through the mountain mahogany on Fish Creek Mountain during a long-ago deer-hunting adventure. Also, I was now coming into the area where the Stolpas got in trouble in the winter of  '92-93. Beyond the pronghorn in the photo above, more or less just beyond the area between that dark volcanic flow and the mountain-mahogany-covered hills, the land slopes east into the upper drainage of Hell Creek, where Jim and Jennifer took refuge in a small cave approximately two miles east of Blowout Mountain. Hell Creek drains into Virgin Creek, eventually into the area of the Virgin Valley opal mines, where they might have found people, had they been able to continue their long trek through the snow. Instead, Jim walked 40 miles or so to Vya, where he luckily found someone at or near the road maintenance station.
Two pronghorn.
The road, 8A, is wide and graveled, quite smooth over most of its length, though it was decidedly dusty. At the north end, the gravel included oversize rocks that make for a rough ride in places. I had the AC on high and recirculate throughout the dirt portion of my trip (from NV 140  to CA 299) to keep the cabin pressurized; otherwise I was breathing in a lot of dust. Every time I'd stop, the dust would move over me from the rear, and I'd have to wait to take photos. The dust, in the mostly still air, was drafting along with the Jeep in lieu of any wind blowing it to one side or the other. By the way, it's always good to check your air filter after a trip through such volumes of dust, or even during if the silt is particularly nasty.
Mesa at the south end of Fish Creek Table.

And then, having passed from northwestern Humboldt County to northern Washoe County, and having also passed out of the Sheldon National Wildlife Refuge, I finally turned onto a side road for lunch. Lunch was accompanied by a short wildflower walkabout.

Moving on from lunch, I came to the fast, western section of road approaching Vya. Finally, the sun came out.

Looking west toward Vya: The playas of Middle & West Lakes are in the center, with Massacre Lake behind the hill on the right. The dark knob on the left is Painted Point.
The 8A portion of the larger trip, from its junction at the north end with Nevada S.R. 140 to the NV-CA stateline where the road becomes CA 299, took about two and a half hours, including several brief photo stops and a 20-minute lunch stop. Google has one traveling that route (63 miles) at an average speed of 18 mph, whereas my average speed including more than 20 minutes of down time, was 25 mph. Before leaving, I had calculated that Google was giving me a rate of 17 mph just for the 140 to Vya section, but apparently they think the entire 8A section is a drag. In winter, of course, one might not be able to traverse the road at all, what with all that volcanic-derived silt turning to sticky, slippery mud, or the plateau country becoming buried or drifted during any serious snowstorm.
Wildflowers near the junction of 8A and 34 south of Vya.
As mentioned earlier, I've been up in the Sheldon country before, most notably many years ago for black powder deer hunting. We were probably somewhere over in the Fish Creek Mountain – Blowout Mountain area, or perhaps a bit to the south down near Mahogany Mountain.

Note: a few photos shown on the map didn't make it to this post.

Year End Sunset Summary

January: a hint of color as the sun goes down
I've only posted four times this year - barely or non-geologic posts - so doing a regular year end summary makes zero sense. So I decided to just pick a favorite sunset photo from each month and post, mostly without comment.
July: the first of many smoky days
August: more smoke
September: most of the smoke is finally gone
October: but not all of it

Happy Holidays everyone!

Snow Day!

Views from my front and back doors this morning. All told, there has been about 6" of snow, 5" shown in the photos.

Color, minor geology

Geology: pencils for drafting cross-sections, hard hat and books, conglomerate.
