Northumberland via old Highway 8A

Before I get very far into this blog post, I have to say that the Blogger interface, with its recent "upgrade," now sucks due to sudden changes in the way the HTML works. First off, the code for each photo is different than it used to be, such that I have to go back to older posts to duplicate spacing at the top, bottom, and left margins. I mean, I guess if I was 100% prolific with HTML, I wouldn't have to do that, but every time they’ve done one of their upgrades, I’ve had to modify the way I enlarge the photos to the right size, and have to recreate or copy the HTML that controls the way my photos display—and quite frankly I do give a damn!

Back to our trip. As I mentioned earlier, it was hot, so I didn't stop very often on my trip down old Highway 8A (now S.R. 305) from Battle Mountain to Highway 50 near Austin, en route to the Northumberland caldera. I did, however, make a point to stop at an old stone house along the Reese River—possibly the original Walters Ranch, though the USGS map shows the ranch down in the green valley closer to the river.
The old place is holding together fairly well, though it looked a little more rundown than the last time I stopped.
A closer view of the entry area, with quite a bit of carved graffiti.
An old rusty stove sits in the ruins of the old stone house, below the caved-in roof and amidst the partly discombobulated walls (stove = dark patch in lower right of photo).
The roof has slumped more than the last time I stopped, which might have been as long ago as 2012. The meadow beyond—the valley of the Reese River between the Ravenswood mountain range on the west and low hills that lie more or less between the Shoshone and Toiyabe Ranges on the east—is often quite green; here it's looking a tad dried out.

At 12:29 pm, toward the end of my little stop, it was 96°F.
A little farther south I drove past the location where FMOH and I canoed meanders of the Reese River back in 2006. This time, the meanders were choked with dark green sedge and the river was too narrow for a canoe. 

My next stop was Austin, for gas. I prefer to be fully fueled when traveling the back roads of Nevada. After fueling up, it was up and over Austin Summit on Highway 50, then up to Bob Scott Summit, where I stopped briefly for a pit stop and to consider Bob Scott as a campsite. But no, I wanted to keep going. Scattered clouds hovered overhead, and a light sprinkle hit the windshield. At 1:20 pm the temp was 84°F.

Beyond Bob Scott, it was downhill to the turn off on old 8A (now S.R. 376) into Big Smoky Valley. I thought about the old camp on Bowman Creek as a possible camping location, but blew that off. I was shortly at the turnoff to Northumberland Canyon.
In this photo, taken just past the turnoff from pavement, Northumberland Canyon is almost 12 miles across Big Smoky Valley as the crow flies. The mountain range that we're looking at, on the east side of the valley, is the Toquima Range; the singular mountain to the right is Mount Jefferson, third most prominent peak in Nevada. I've been to about 11,400 ft near the North Summit. The South Summit reaches 11,941 ft.
I arrived at the western mouth to West Northumberland Canyon at about 2:30 pm and pulled off on a side road where I had a relatively elevated view of Big Smoky Valley and the Toiyabe Range beyond. A low area in the mountain range (just left of center in the photo above) marks the drainage basin of Kingston Creek. The tiny town of Kingston sits on Kingston Creek, right at the range front. Bunker Hill, the rounded peak right of the low spot, reaches 11,473 feet in elevation.

* * * * *

2:45pm: It's now 92°F. I just walked a short ways up the dirt road behind the Jeep, thinking I'd check the road to the range front, but I gave that up for the heat. Instead, I'm sitting next to the Jeep in a lawn chair, enjoying the view. A few clouds overhead look threatening—possible T-storms. I won't cross the flash-flood prone Northumberland Canyon dry wash until...well, hopefully the clouds will dissipate. The crossing right now would be perfectly fine, but if the canyon floods, I'd be stranded on the other side. A long time ago, there was a road across Big Smoky Valley going back to 8A north of Kingston, providing a possible escape route if stranded; I have no idea if that road exists anymore.

There was a huge wipe out of a flash flood in West and East Northumberland Canyons back in 1979. Heavy barite ore from the small mine on the west side of Northumberland Pass was washed down canyon, as was a USFS truck. Fortunately no one was inside the truck.

Back in 1978, in the reddish hills across the dry wash of West Northumberland Canyon (behind the Jeep in the photo above, or somewhere in the low part of the reddish hills in the photo below) I left a standard Estwing rock hammer leaned against an outcrop of tuff as scale for a photo. I've looked for the hammer a couple times, both before and after the mega flash flood of 1979. I suppose it's part of the drainage, downstream somewhere. But who knows? Maybe it's still there, leaning against the outcrop.
The reddish brown tuff of Hoodoo Canyon, 31.4 Ma, overlies whitish volcanic and volcaniclastic rocks that include Ts6, an air-fall tuff related to the tuff of Hoodoo Canyon, and Ts5, 4, and 3—and possibly Ts2 and 1—which are all intracaldera sediments deposited after the partial collapse of the ~32 Ma Northumberland caldera and before deposition of Ts6.

2:53 pm: I've frequented this valley, these parts, since before 1978. In fact, the first time I camped in the area was up on Pete's Summit in 1976, after seeing the Ordovician graptolites in the Vinini Formation while on a grad school field trip. It's my country, I feel, and if I had a house up here on this pediment, I'd sit outside and stare at the basin, the way I did back in 1979-81 when the company put me up in a small cabin above Kingston. There's usually no no one around for miles, for at least ten to fifteen miles. The view is awesome.

It's 4:27 pm now,
and I've crossed the wash and moved to the site we used to call the Hot Spot, so named for it's anomalous gamma radiation and U3O8 minerals. From the camp I've chosen, I can look northwest toward Kingston Canyon, east into Hoodoo Canyon, and south toward Northumberland Canyon. The wind is coming in from the northwest, and it's 91° F in my little camp. It's five hours to sunset according to the hand method, though at five hours away, the method is grossly inaccurate.

4:51 pm: I'm cracking an All Day IPA. Until the sun is lower, I won't set up camp more than I have already, which is only to remove the ice boxes, the water cooler, and folding chair. I'm somewhat low on ice, and the beer isn't the coldest beer in the world, but it's refreshing. And now the sun has come out from behind those formerly threatening clouds, so I've moved into the shade of the Jeep. A tree would be nice!

* * * * *
As the sun got lower, I drank my cool beers and had a minimalist dinner of chips and dip. The sun finally went behind the clouds hovering over the Toiyabe Range. I watched the sunset colors change, took many photos, marveled at the yellow-orange crepuscular rays, took more photos, and basked in the quietude of the area.
Virga and a cliff of Northumberland Tuff glow reddish orange.

I had another beer or two and took more photos. At some point, the sun went down, but with the Toiyabes in the way and no connection for my cell phone, I could only estimate the time of actual sunset, guessing it to be about 8:05 pm. According to SunCalc, the sun set at 8:10 pm at my campsite. The hand method referenced earlier gave a time of about 9:25 pm—off by almost an hour and a half! (It's more accurate within one to three hours of sunset, especially when there aren't any mountain ranges looming above the true horizon.)

By 8:43 pm, I had my headlamp on, using the red light setting. It was way warm for sleeping, but I didn't check the temperature by turning on the Jeep. Overall, it felt strange to be camped there in the middle of nowhere during the middle of a summer heat wave. And for some reason, I felt creeped out by a long ago memory of a lone mountain lion in the Toquimas, so I didn't want to sleep outside the Jeep, making for a night that was hotter than necessary. Eventually, I slept, albeit restlessly.

Well, it's been so long...

It's been a long time—almost a year—since my last real post, the actual last post being a road song with brief blurb. And even though it's been a year, I haven't really started what would be the last in a series of posts reporting on a trip from Winnemucca to northeastern California, with geology and other points of interest along the route. It's been hard getting to that last post and to a few side posts along the route that would be possible if I would just maintain a bit of focus. And the stumbling block is basically that I'm not traveling that way anymore, at least not routinely: I don't live at that end of the road. Yeah, "the lake" is a thing of the past (which is really sad, especially given the exceptional heat that the summer of 2020 has brought to the northern Nevada area where I currently live).

Anyway, that's a roundabout way of getting around to saying...it's been a long time since I visited the Northumberland caldera in central Nevada. The current isolation of living by myself, social distancing to the extent of hardly seeing anyone who doesn't happen to be in line behind me at the supermarket, and WFH—which I've been able to do so far for exactly two months since leaving "the field" of northeastern Nevada—was starting to drive me nuts, as it does periodically, and I wanted to get away.

Unfortunately, it's been very hot here in northern Nevada (and elsewhere in Nevada, and in many other parts of the west), so though I contemplated going on a brief camping trip, it seemed too hot for that (did I mention the heat?), and the upper campground at Wheeler Peak is closed for renovations (I consider the lower camps to be both too hot and too crowded). So, with the highest, coolest camp in Nevada out of the question, I opted for a central Nevada area that I've been familiar with since 1978: the Northumberland caldera.

Yeah I thought, maybe I'll camp in the highlands, up in the piñon-juniper, but I was unsure of any specific places up there so was sure I'd opt for the more familiar lowlands. Eventually, after much dithering accompanied by equally much grousing about the heat and why it's not a great time to go camping, all the while and nevertheless preparing, then reverting to no it's too hot, then more prepping, then etcetera, off I went.

The trip was a reprise of many, and because of the heat (the highs were around 100°F) I made few stops on my way out to an old drill site atop a location in the northern part of the caldera that we at NEC (Northern Exploration Company) called "The Hot Spot."

The Hot Spot (photo above) is a fairly small mound-like outcrop of welded ash-flow tuff (tuff of Hoodoo Canyon) mineralized with carnotite replacing feldspar sites. At least I think it's carnotite. Maybe it's autunite. That mineralogic tidbit is somewhat blurred by time. I didn't break a single rock out there this time, so didn't check the uranium mineralogy. I did, however, collect a couple nice hand samples of Ts2 and Ts3, formations within the intracaldera sedimentary package.

Anyway, I ended up at the Hot Spot, spent an overly heated night camping in the back of the Jeep, and then I returned via a slightly different route the next day, a partial reprise of trips made in the region as recently as 2012, a time which seems almost as long ago as those first days in 1978.

Wandering Amongst the Granite Knobs in the Northern Sierra

Granitic knobs in the northern (way northern) Sierra.
It's been a busy summer, such that I really haven't had time to get much blogging done—and I had so many good posts planned! But it's been really difficult for me to do much of anything while working essentially twelve to fourteen hour days (depending), and on days off I've been working around the house, gardening, and attending to other things besides writing.

Nevertheless, MOH and I have found time to get out and about a couple times; these photos were all taken on a particular jaunt of ours back in early July. While traversing from west to east across the Great Basin Divide, we unexpectedly drove by some lovely exposures of granite—well, probably it's technically granodiorite.
It was just barely past spring at our elevation of 5500 feet.
Pinemat (Ceanothus prostratus) takes over a stump.
From our parking area beneath tall pines next to a spring, we wandered up to the the closest knobs.
The view southward from our "Granite Hill."
From this perspective, it's easy to get a feeling for the magnitude of several wildfires that have burned through this area in fairly recent years. At least two, maybe three, fires were evidenced by different tree heights.
Upward we climb.
I think exposures of granite and other granitic rock are fascinating, and it's hard not to stop and stay all day, even when the day is a scorcher.
A wildflower has taken hold along a fracture or joint.
This bouldery countenance reminds me of the tufa formation "Old Woman with Basket," also known as Stone Mother, on the east shore of Pyramid Lake.
Looking off to the north, as the last photo does, it's easy to see at least two plantings of Ponderosa Pine, which followed two or more forest fires. As the trees grow, forest managers come along and thin the trees.
This tree was five to nine years old when cut, depending on how one should count the rings.
Here are a few of the great mafic inclusions we saw while wandering around.
Some vertical joints within the granite.
A cobble got stuck in one of the vertical joints.
A swarm of inclusions!

Way Too Much Smoke: Volcanoes (and Rivers and Ridges) in the Pacific Northwest

Mt. Jefferson
There I was minding my own business while flying north from RNO to SEA (that is to say, I was reading a thick book and trying to ignore a seatmate while crammed against the window near the rear of a Q400), when I looked out (to the east) and spotted the peak of an Oregon volcano sticking out through what I first thought was a low, thick cloud cover. I grabbed a few quick shots through a badly spotted and smeared window, while rapidly revising my reckoning about the cloud bank: no clouds, just a very dense blanket of smoke.

Whereas I first estimated I was somewhere over central Oregon south of Sisters or Bend, it soon became apparent that I was probably a little farther north than I thought — and it turns out I was between Sisters and Portland looking at Mt. Jefferson (first photo).
Mt. Hood
The photo above shows Mt. Hood barely sticking up above the dense smoke bank. Hard to say exactly, but it looks like the smoke is about 10,000 feet thick! Hood's peak sits at an elevation of 11,240 feet, and its south shoulder sits at somewhat above 10,400 or 10,600 feet (depending on what part of the shoulder we're actually looking at); the Portland outliers of Troutdale and Springdale in the foreground have elevations of about 100 feet and 300 feet, respectively. As a geographical point of interest, the larger, streamlined island on the north side of the wide Columbia River is Reed Island. The river beyond the island fades gradually and then disappears abruptly in the distance.
Mt. St. Helens
My first view of Mt. St. Helens was of what I call the back side (the south side). It's clearly not an ordinary Cascade volcano by today's standard of nice, symmetrical peaks, although several Cascade volcanoes are known to have created lateral blasts like the one St. Helens produced in May, 1980 — and maybe all or most have done something like that sometime in the past.
Mt. St. Helens
This second shot of Mt. St. Helens (above) shows the South Fork of the Toutle River in the foreground and Spirit Lake in the background.
Mt. St. Helens and Mt. Adams
Mt. Adams can be seen in the distance, barely sticking up above the smoke, even though it reaches an elevation of 12,277 feet!
North Fork Toutle River
This view of the Toutle River (Google Maps location) shows an area just above the Toutle River Sediment Retention Structure. The berg of St. Helens sits across from a green, tear-dropped-shaped "island" that is marked as hill 11227 on some topographic maps (e.g. this one at the USGS TNM 2.0 Viewer).
Smoke amid the low hills between Mt. St. Helens and Mt. Ranier
One last look at Mt. St. Helens
Mt. Ranier
Mt. Ranier, the tallest Cascade volcano at an elevation of 14,410 feet, rises above the smoke more than any of the others. The clouds obscuring its peak make it appear to be erupting (it wasn't).
A last view of Mt. Ranier, seen as the airplane descended toward SeaTac.
Smoky wisps interfinger with some low hills north of the airport after take off several hours later.

Too Much Smoke — And Pelicans!

It's a little hard to tell how smoky it is from this picture, until you realize that Lassen Peak, the central feature of the Lassen Volcanic Center and Lassen Volcanic National Park, should be easily visible just to the left of the distant part of the highway. Here's what this same view looks like on Google Street View (or see the next-to-last photo of this post).

Yes, it's been very smoky in northern California this summer, as it has been in many places across the west. These particular photos were taken on August 21st, when I just happened to drive down the right roads in the right direction, i.e., westerly, so it was easy to notice that Lassen was essentially missing.
Mt. Harkness is on the far right; Kelly Mountain is a little left of center.
Lassen should be where the faint smudge is in the photo above, immediately to the left of Kelly Mountain.
Here, a little farther down the road, Mt. Harkness is on the horizon on the very far right, just above the highway; Kelly Mountain has disappeared below the the sloping, forested horizon. Lassen would normally be standing out just near the center of the photo (Google Street View location).

Kelly Mountain *might* be part of the far, outlying flanks of the older, larger volcano known as Mount Tehama, but *might* is a speculation on my part, one not based on much geologic research (or any mapping!).

The road took me by an overlook of the northwestern end of the hazy, smoky Lake Almanor. The lake is very low for this time of year; it has nevertheless been host to lots of pelicans, egrets, Canada geese, and many other waterbirds including occasional sightings of blue heron, and the often ubiquitous coots.
Six pelican swim away from me above the lower left blue patch; two egrets stand like symmetrical statues toward the right.
I could see Lassen Peak clearly on August 24th; the photo location approximates that of photo #1.
Lassen Peak looms above the darker, tree-covered Kelly Mountain, from a location close to photo #2.

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 2012201120102009 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).
