Good Evening, from 11-6
See my in-depth writeup of my Mercedes Sprinter photography adventure van.
That is, from 11,640' elevation / 3537 meters.
iPhone elevation readings cannot be trusted even in near-optimal conditions. See note that follows
I felt like playing a little today, after working 18 hours straight + 5 to finish a project to be published in a few weeks (not including the all-day hike).

It was a austerely beautiful evening driving up tonight into the White Mountains of California. I saw one vehicle—descending. A little Mozart seemed about right driving up in my Mercedes Sprinter photography adventure van, and while writing this.
The iPhone sucks (so hard to get desired focus and exposure and then massive noise at dusk), but when it’s handy it’s peachy.

Might be a little cool tonight...

I don’t mind the cold much, but with the wind, it might dip down to 18°F or lower inside the Sprinter tonight.

Good thing I have both the immensely useful Western Mountaineering Cloud 9 comforter as well as the roomy 850+ fill power down Western Mountaineering Cypress GWS sleeping bag which is really 910 fill power, a quality of down that is more or less unobtanium for anything out there—rated for down to -30°F / -36°C.
I think that will be just fine; I like partially unzipping the Cypress and using it blanket style. The Cypress sleeping floated on Greenstone Lake for 30 minutes while I shot all sorts of angles, but the down never got wet thanks to the GWS fabric.
Update: it actually got a little colder than I had thought: 16°F (image at left). The Cypress GWS was actually too warm at 31°F inside, even partially unzipped. I had to leave it unzipped about 18 inches to not be too warm down to the low temperature last night.
Update 2: it turns out that altitude shown by the iPhone 7 Plus cannot be trusted . Actual altitude was about 150 to 200 feet too high, in spite of the misleading and false claim of ±13.1 ft. This makes sense: I’ve owned several GPS handheld units, and altitude has always been a weak spot with GPS. Here I was at very high altitude and with a horizon to horizon view in all but one direction, so the iPhone had a full constellation of GPS satellites—and it still could not get it right. Climbing 300 feet up the mountainside, the iPhone showed me being at the same altitude as before climbing, this time with the ridiculous claim that accuracy was within 9 feet. Maybe it was, maybe it wasn’t but after the climb I was on a high ridge with an almost 100% horizon to horizon view.

Below, taken about 3 weeks earlier. No way was I going out tonight at 22°F with the wind blowing.
