An area near “Rim of the World” recently burned by the Rim Fire

Late this past summer one of the worst wildfires in the Sierra burned extensive areas near and within the northwest “corner” of Yosemite National Park. The “Rim Fire,” as it has come to be known (since it started near the “Rim of the World” overlook) came at a time of very bad conditions – in hot and dry weather, late in the season, and at the end of a second drought year in California. The first spread very quickly, and it took tremendous efforts to contain it – and full suppression took many, many weeks.

Since the fire burned in areas that I know very well from decades of travel through this part of the Sierra, I was anxious to see the extent of the damage. At first I thought I might get a chance in early September, when I traveled back and forth to the eastern Sierra to photograph fall colors. However, weather interfered – snow closed Tioga Pass Road and I ended up taking different routes across the range. Finally, at the very end of October, on a drive to Yosemite Valley I passed this way early in the morning. Overall, from what little I could observe, several things seem clear: the fire burned a very large area, some sections were very badly damaged and it will be a long time before trees grow there again, other sections were only lightly burned and a few were skipped over. This view, from the “Rim of the World” overlook, rises from the close charred hills above the Tuolumne River Canyon, across more distant ridges, and culminates at far peaks with a light dusting of early season snow. All of the conditions I described above are visible here – serious destruction in the foreground, a bit further in there are some trees that were burned by not killed, and far beyond there is forest that appears to have not been burned.

About the Yosemite “Rim” fire… and more

UPDATE and a NOTE:

Update: Shortly after I posted this, my reports on highway 120 through the park via the Tuolumne Meadows area  were rendered incorrect/outdated by way of an updated announcement from the park service as follows:

“Beginning at 12:00pm on Wednesday, August 28th, Tuolumne Meadows and the High Sierra will only be accessible via Highway 120 East through Lee Vining.  The Tioga Rd/Hwy 120 East will be temporarily closed between White Wolf Lodge and the Big Oak Flat Rd./Hwy 120 West at Crane Flat; the closure is estimated to be 3 to 4 days.  Tuolumne Meadows Lodge, the High Sierra Camps, and Tuolumne Meadows and Porcupine Flat campgrounds all remain open.”

Basically, this means that you will not be able to use highway 120 as a route across the Sierra until further notice. I’m not surprised – in fact, I’ve been somewhat surprised that the road remained open this long. Apparently the following URL is also a good source of updates from the park: http://www.yosemitepark.com/yosemite-fire-update.aspx

Note: All of which brings me back to my original statement that I don’t have inside information on this fire, and that anyone traveling to the area needs to check official sources for conditions updates. I will likely not update this page as things change, so the information posted here should be regarded as potentially being out of date!

My original post follows…

—

A few people have asked me for information about the “Rim” fire which started not far from Groveland near highway 120, and which is currently burning along the northwest boundary of Yosemite National Park, generally moving east and north toward the highway 108 area. While I know much of this area fairly well from many years (decades, actually) of visits, I do not have any inside information about the fire itself, nor am I an expert on wildfires. One good source of (limited but objective) information is the Stanislaus National Forest Rim Fire Incident web page. A map on this page is a quite amazing source of information, especially when combined with some familiarity with the area and a reading of various written reports. (The version on the main page seems to be based on Google Maps, and allows you to scroll around and zoom in.) Lots of folks who live and work in the area are sharing updates on the usual social media sites. The Mariposa Gazette is another local news source.

The fire started on August 17 more or less midway between Groveland and the  northwest park entrance and not far off of the highway 120 corridor near the Rim of the World area overlooking the canyon of the Tuolumne River. (Highway 120 is a common route for entry to the park from the west and northwest, and it connects via Tuolumne Meadows and Tioga Pass to the east side of the Sierra at the town of Lee Vining.) The spread of the fire at first was somewhat quick, which is no surprise given the extremely dry conditions in the Sierra following a second very dry winter and almost no real precipitation since late 2012. Then, between about August 20 and 23, the fire exploded, expanding  very quickly to cover a huge area generally to the east and north of the starting point, with the fire generally racing northeast but also spreading to the north and south.

Powerplant, Railroad Avenue – Mare Island Naval Shipyard

Powerplant, Railroad Avenue – Mare Island Naval Shipyard. Mare Island, Vallejo, California. February 27, 2010. © Copyright G Dan Mitchell – all rights reserved.

Night panoramic photograph of the powerplant building and other structures along Railroad Avenue at the historic Mare Island Naval Shipyard, Vallejo, California.

This is a bit of a first for me – a night photography stitched panorama. This image is composed of two separate exposures which were aligned and “stitched” into a single image in post. (As such, it could be a very large print!) Shooting from an elevated position, I shot almost directly north (as you can tell from the star trails in the larger version). The view looks up Railroad Avenue past the iconic power plant building with its smokestack that is visible from all over Mare Island.

I’m usually a bit casual about exposure time with long exposure night photographs. It isn’t that I don’t care – it is just that one has a ton of leeway when it comes to the very long exposures I typically use. For example, on a 3 minute exposure you would have to be off by three minutes to overexpose by one stop! So rather than use a stopwatch or an automatic timer I just count to myself. I’m usually will within a 10% error, and that is good enough. However, when stitching “good enough” often isn’t. The separate component frames really need to be quite similar, so in this case I resorted to using my watch to get relatively accurate 90 second exposures.

Another interesting factor in night photography is illustrated in this photo, namely the wildly varied colors of the light sources we deal with. There are three dominant sources in this image. The overall illumination comes from the full moon, which is quite similar to day light in terms of white balance. On the near wall of the brick power plant there is very “hot” and saturated yellow/red tinted light, probably from sodium vapor lamps. Near the left end of the image is an old wooden building that is illuminated by very green light, which I believe comes from mercury vapor lamps. I often chuckle a bit when people speak of “white balancing” the color in a scene like this. If you pick one source for your white balance you’ll throw the others even more out of line. My philosophy is usually to just go with what looks right!

Finally, the idea of making the stitched panorama came from the recently started Panocturnists web site, begun by people connected with The Nocturnes, the San Francisco Bay Area night photography group. I was intrigued by the idea of creating panoramic night photography, and I’ve done a few images along these lines on my two most recent visits to Mare Island.

Ship Yard Towers and Fog, Night

Ship Yard Towers and Fog, Night

Ship Yard Towers and Fog, Night. Mare Island Naval Ship Yard, Vallejo, California. August 30, 2009. © Copyright G Dan Mitchell – all rights reserved.

Night photograph of tall ship yard towers and old buildings backed by glowing fog at the historic Mare Island Naval Ship Yard, Vallejo, California.

OK, I lied. I do have more photographs from my late-August night photography shoot at the historic Mare Island Naval Ship Yard in Vallejo, California.

This one includes the view up Nimitz Street past the main ship building area and the includes the huge overhead structures apparently used to move equipment from the shops to the dry docks and the waterfront. The scene is backed by the strange glow of the ground light sources illuminating the high fog coming in from the San Francisco Bay.
