Winnemucca to Hwy 395 north of Susanville, Part4

And now we’ll say goodbye to the Smoke Creek Desert, which we saw on the last leg of this cross-country journey, and make our way south for a very short distance, where we’ll turn off the road skirting the entire west side of the desert, and head west up Smoke Creek. Photos you’ll see in this blog post are from three different trips taken between the Smoke Creek Desert and Highway 395 during May through August of 2006, 2014, and 2015. Which means that although we’re returning to my June 15, 2018 trip from Winnemucca to Susanville, which began here,I didn’t take any photos during this section of the 2018 trip.
Immediately upon leaving the great tufa mounds of the last post, we come to a hill with a view of distant trees that are growing along lower Smoke Creek. The sign indicates our upcoming turn onto the Smoke Creek Road. The smaller, hand-painted white sign says “Smoke Creek Road,” so we know we’re on the right track. (Photo: 17May2014.)
On the left side of the road, just as we turn right, a bullet-ridden sign points south toward Sutcliffe, a small town on the west side of Pyramid Lake several miles beyond our turn. This will be our last view of the Smoke Creek playa and the Fox Range to the east. (Photo: 14Jun2006.)
We’re now heading about due west toward the valley of Smoke Creek. In this area, a lot of the creeks and canyons are named on USGS topo maps, but very few of the hills are. As an example, the highest point on the volcanic-covered hills above is merely marked with an X and the elevation 6186 feet, along with a small triangle for a survey point with the name Smoke. (Photo: 17May2014.)

The basaltic hills, and the sagebrush in the foreground, were fairly green in mid-June of 2006. The buff-colored hills are underlain by Lake Lahontan lake deposits, possibly the Sehoo Formation, which are inset into the older, Miocene basalts. (Photo: 14Jun2006.)
We’re about to round the bend and drop in the valley of Smoke Creek. (Photo: 17May2014.)
Here you can possibly get a better idea of the younger lake sediments being inset into the canyon, such that although the buff-colored deposits are lower in elevation than the reddish brown basalt flows, they are not underlying them in a stratigraphic sense. This hill also shows the first example of Lake Lahontan tufa plastered on basalt (pale brown tufa on dark brown basalt in the upper left part of the photo). (Photo: 17May2014.)
The older sediments that underlie the basalt have been baked to a bright red color in this view not far up the canyon. (Photo: 14Jun2006.)
And there’s more! A large mass of light brownish tufa sits atop vaguely spheroidally weathering dark brown basalt. For locations of these photos, check out the map linked near the end of the post. (This and next photos from 15Aug2015.)
Less than a half mile from the sharp turn near the west end of the canyon, we come upon the “Cave in Smoke Creek Canyon,” which is along the Nobles Trail section of the California Trail.
“There is a cave ... in this canon, the entrance of which will admit a man on horseback several of the company having entered on horseback but I do not think that they saw much for it was dark as pitch in the cave” – Mary C. Fish, Sep 7 1860
The signs along the various trails are maintained by Trails West. A photo tour of the trail can be found on their website here.
Our first view of the mouth of the cave, as seen when coming in from the east.
A closer view.
The cave with wild roses in bloom. (This and next photos from 17May2014.)
The cave has plenty of room overhead, and people obviously camp within. The roof is darkened by soot from many fires over the many years.

Across the creek from the cave, I spotted a cinnamon teal

Winnemucca to Hwy 395 north of Susanville, Part 3

Black Rock Desert
Well, here we are again, traveling from Winnemucca, NV, to Highway 395 north of Susanville, CA, and we’ve just made it to the west end of the Jungo Road where it intersects with NV S.R. 447 (formerly S.R. 34) just south of Gerlach. You’ve probably noticed that I haven't been blogging much recently. I'm not really sure why. Sometimes the work I do takes the writing right out of me, partly because I do enough writing many days that I'm totally done with that by the end of the day; also, I don't really have much time after work before I have to do dinner, then get ready for bed—at least if I want to get enough sleep, which I do want (I don't always succeed). Another thing contributing to the recent spate of sparse blogging—besides taking care of personal things that have been taking a lot out of my energy during my days off—is that my writing effort during the fall and winter months has been going toward writing bits of fiction (a novel?), which I've been working on intermittently during the last two years.

Anyway, all of that—work, trying to get enough sleep, personal issues, and writing fictional to non-fictional stories—has placed blogging low on the list.

Now I'll upload the photos for this post, and we'll go from there. Just like a real journey, we’ll see how far we get!
Smoke Creek Desert
At the end of the last post, we'd driven quickly through Gerlach and had reached the northwest side of the Smoke Creek Desert. I hadn't taken any photos while zipping through Gerlach, but I often stop, and I've even stayed overnight at least twice. So let's backtrack before moving on.
Gerlach is a small town that brags of several mottoes, including "Center of the Known Universe," "Where the Pavement Ends and the West Begins" and "The Time That Town Forgot." More can be seen on the town sign, above, or in this nicely enlarged version of the sign by the RGJ. As indicated by the sign, Gerlach is technically pronounced Grr-lack rather than the Grr-lock one hears so commonly these days. I shot these photos of Gerlach on a trip that FMOH and I took back in the spring of 2014. Like the June, 2018, trip that we—you and I—are reprising, he and I had just come into town from Winnemucca on the Jungo Road. We were bringing the motorcycle back from Nevada, mirroring this trip taking it out to Nevada.
While in town, we did the usual thing of stopping to eat at Bruno's Country Club, probably getting Bruno's Famous Homemade Ravioli. By 2014, Bruno was no longer making his ravs personally, so I don't think they were quite as authentic, nor were they quite as good.
Unlike many trips, this time we stopped at the bar for a couple beers; we weren't driving on that afternoon or evening, but were, rather, staying at Bruno's Motel. Bruno Selmi, the Basque owner of the cafe, bar, motel, and only gas station in town, died in May of 2017—he can be seen in the photo above the bar (the older man on the right).
After checking in to our room at the motel—and after duly going back to the bar to get a second room when the first smelled either of gas or dead mouse—we wandered out onto the far western edge of the Black Rock Desert, where we had a view somewhat atypical of most views of the desert. This section of the Black Rock is a section you don’t want to drive into: it’s usually muddy, and it’s very possible that you’ll get stuck. The getting stuck part typically happens at night when an unsuspecting traveler, one who is already out on the desert somewhere to the east, decides to get off the desert—and instead of driving to the usual take-out spot north of town, sets their sights on the lights of Gerlach and makes a beeline for town. The next thing our unsuspecting—or willfully ignorant—traveler knows, they are stuck, possibly axle deep, in the mud at the west end of the main section of the Black Rock Desert. Fortunately for them, they aren’t far from Bruno’s gas station. Maybe someone will risk a vehicle to come and pull them out!
It’s possible one could wend their way through the merely salty white section of desert to the pavement on the east edge of Gerlach, at least in the drier years, but I don’t recommend trying it. I personally know at least one person who tried this one night back in the 1980s; the getting stuck was epic.
The next morning after breakfast, FMOH and I headed west.

Now let’s get back to my June 2018 trip, which I was taking all by myself (cue pint-sized pity party). I had just made it to the northwest side of the Smoke Creek Desert and had taken the photo seen earlier and in my last post.
A ways farther down the west side of the Smoke Creek Desert, I pulled over for a quick examination of some tufa. There are many spots to see tufa domes, mounds, and hills along the west side of the Smoke Creek Desert; this mound, Hill 4081, was a new one to me.
I climbed up through the cheatgrass and scattered tansy-mustard tumbleweed and looked around. Here we’re looking off to the northeast, more or less back toward the Junction of C.R. 447 and the Smoke Creek Desert Road. The Granite Range, unsurprisingly underlain by granite, rises steeply beyond the distant Smoke Creek Desert playa. The foreground is green because...water. It’s a wet part of the basin, possibly because of the entry of perennial Smoke Creek into the desert just south of where we’re standing. It’s also more elevated than the playa, and covered with grass (at least cheat grass) and various scrub.
I love tufa mounds, so I stood looking around for a few minutes, taking lots of photos. This photo looks off more to the north. The distant bluish hills just right of the tufa dome are part of the Buffalo Hills, which are underlain by a pile of volcanic rocks.
More tufa! More volcanic rocks! The hills in shadow between the tufa masses are some volcanic flows forming the eastern foothills of Burro Mountain.

From this point on Hill 4081, I got back on the Smoke Creek Desert Road, went south a short distance, and then turned west on what Washoe County considers the continuation of the Smoke Creek Desert Road, and what Google Maps refers to as the Smoke Creek Road: a dirt road that heads west up Smoke Creek.

From the Road: Conway Summit


I'm having a little trouble keeping up with the road trip--for one thing, the mobile app thingy doesn't really work very well, so it's easier to just wait until I have wifi, and I don't get any of that when camping (!)--but here are two photos from Conway Summit.

The first looks south at Mono Lake. The Sierra Nevada is on the right, and the White Mountains are on the far left (they don't look impressive in this photo, but they are). The Mono-Inyo Craters, with the caldera rim of the Long Valley Caldera beyond it (they are indistinguishable in this photo) form the hills that provide a nice backdrop to Mono Lake. You can barely see Paoha Island in this photo; it's the light-colored island behind the dark land mass left of center. The dark land mass is Black Point, a 13,300 year old basaltic cone. Negit Island is easy to see: it's the smallish, dark-colored band to the left of Paoha and Black Point. Paoha and Negit are both volcanic islands, although it looks like the lake is low enough that Negit is not currently an island. The lake looks really low--I thought they were maintaining it at a higher level; maybe it's the drought, maybe the water accord has failed.

The roadcut across from the Conway Summit pullout (just below Conway Summit, actually) exposes grusy, unglaciated granite. There's also quite an exposure of glacial till in the hill above the granite, and in the hill and roadcut leading up to the summit proper, which you can see when driving north or south on 395.

Dust Storm at The Needle Rocks, Pyramid Lake

It was a very windy day as I drove south along what's variably called the Surprise Valley Road or the Sand Pass Road (and to the north, is often called the Smoke Creek Road) into the Pyramid Lake Paiute Tribe's Reservation.
Various signs at the north entrance to the reservation.
I could see the dust -- and the faded outline of the Lake Range beyond the curve. The signs are located at the north end of Reservation Route 2, according to this map. I wasn't really thinking about the names of the ranges or the numbers of the road while driving, I was really focused mostly on the wind and dust!
Soon, The Needle Rocks came into view.
A modified view, as if I were still into shooting B&W film.
Now we can see the bright turquoise color of Pyramid Lake. And still the dust.
I'd highly recommend not going out the The Needles in such a storm (and besides, it is closed these days) -- a few of the higher shorelines of the lake (of Lake Lahontan) are composed of tiny snail shells (Pyrgulopsis nevadensis, photos here, here, and here) -- and you really don't want those sharp tiny things caught in your eye!
The wind was really whipping up the dust.
Looking back from farther south.
I had a pretty good view of part of the Terraced Hills beyond the dust, and could see part of Wizards Beach and Wizards Cove, but most of the individual rocks at The Needles were well obscured (USGS TNM 2.0 Viewer map). The wind looked to be blowing in from the west or northwest.
A closeup from the same place, with a good view of rock 3935 out in the lake, and an obscured view of the tip of The Needles and tufa mound 4107.
And finally, I looked back across Thunderbolt Bay from near a green area marked Pyramid (USGS TNM 2.0 Viewer map, USGS GNIS locale "Pyramid").

Textures from a Tufa Dome III

These are the last photos from this short mini-series showing textures of tufa from a tufa mound near Trinity, Nevada (read more about it and get directions to the spot here).

These photos show what appear to be a piece from the outer edge of a formerly spherical part of the tufa mound, like one I described here earlier, and ones seen in Figures 18 and 19 from Larry Benson's 2004 circular, The Tufas of Pyramid Lake.
Enlargement of the same piece.
I like the first photo for showing the bright orange lichen in the background. The second photo, besides being an enlargement, shows some pale to medium yellow lichen on the piece I'm holding.

Textures from a Tufa Dome II

Here's one more quick photo in this short-lived (and widely spaced!) series showing some textures found around a tufa dome near Trinity, NV, which is described more fully here. These are fan-shaped plates, probably originally composed of thinolitic tufa, possibly now calcium-carbonate cemented as in this photo from Pyramid Lake (page-up slightly to see the photo).

Textures from a Tufa Dome I

Just a quick post in a new, short-lived series of photos of tufa from a tufa dome. The dome is discussed in more detail here, a post which includes directions to the dome from the junction of I-80 and U.S. 95 at Trinity.

Tufa Dome north of I-80–U.S. 95 Juntion

A somewhat eroded tufa dome.
Every now and then, when driving east or west on I-80 in northern Nevada, I get off and check out local items of geological or historical interest.

Here I've stopped at a partly eroded tufa mound located north-northeast of the junction of U.S. 95 and I-80 (map and location below). It's fairly easy to reach with an SUV or other 4WD vehicle.
View of the tufa mound looking northward toward the low hills of the Trinity Range.
Another view, this time with more of the basaltic-looking hills in the background.
Closeup of some the tufa structures, looking in toward a small crevice.
I tried focusing on the tufa textures in the foreground and background at the same time, but it was a cloudy day: not quite enough light.
Tufa covered by bright orange lichen on the north-facing side.
Looking south toward the U.S. 95–I-80 junction, and 95 beyond that going south toward Fallon.
The view above shows the eastern part of the White Plains of the Fortymile Desert, with the west end of the Mopung Hills of the West Humboldt Range in the left part of the photo (MSRMaps location).


Embedding this map directly from Scribble Maps (see original map here); didn't work, so I imported the "scribble" to Google Maps.

To get to this particular tufa dome (there are many in the general area between a few miles east of Nightingale Hot Springs and Toulon), take I-80 exit 83 from either the eastbound or westbound lane. If going west, turn right nearly immediately (at a location known as Trinity, now with former buildings gone), and follow a paved road to the north-northwest. If going east on I-80, turn left from the off-ramp onto highway 95, go under the I-80 underpass, follow the road as it curves to the east, and turn left on the same paved road just before entering the on-ramp loop for Reno and points west.

Drive about 0.3 miles on the paved road until you reach a power line access road, a dirt road that may not be appropriate for cars. Turn right, taking this road for about 0.7 miles, including a deviation from the power line itself, where the original road is at least partly washed out. You will then reach just the right sand wash road, which will take you up to the tufa dome (and beyond to a small prospect). I can't say for sure that the turn I marked into the wash road is exact; look for tracks heading in the right direction.

Careful examination of a Google Maps or Google Earth view of the area will reveal another road that comes in from the west just uphill from the tufa dome. I have no idea whether this road will work as an access route, but it will (or would?) go past a couple other domes.

While there, note the several Lake Lahontan shorelines and the desert pavement.
