It is clear from AA's description that the location from which he photographed is on a road:
"Clearing Winter Storm came about on an early December day.... I drove to the place known as New Inspiration Point, which commands a marvelous view of the Yosemite valley.... At this location one cannot move more than a hundred feet or so to the left without reaching the edge of the almost perpendicular cliffs above the Merced river. Moving the same distance to the right would interpose a screen of trees or require an impractical position on the road.Moving forward would invite disaster on a very steep slope falling to the east. Moving the camera backward would bring the esplenade and the protective rock wall into the field of view."
This description seems to match Tunnel View (http://www.nps.gov/yose/naturescienc...unnel-view.htm) well. The term "esplanade" in particular suggests a paved or tarred area that is not a road, which is what can be seen in the third photograph on the referenced website titled "Visitors take in Yosemite's famous scenery, including of the Valley, from Tunnel View on a summer day in 1940", complete with protective rock wall. The perspective over Yosemite also appears correct. It is easiest to compare perspectives in Yosemite Valley, Summer, Yosemite National Park, c. 1935 (plate 2) since the distant mountains are not obscured and their location relative to the nearer mountains can be compared with the photograph taken from Tunnel View and shown in the web link. However for me the most telling is the location of the light gray areas surrounded by green on the rising slope on the left of the national parks board photograph. These appear almost identically and very clearly in Yosemite Valley, Summer, Yosemite National Park, c. 1935 and quite recognisably, though less clearly, in Clearing Winter Storm. Since this appears in the near middle distance, the locations from which these photographs were taken must be very close.
So I agree that Clearing Winter Storm and the other photographs with the same perspective were in fact taken from Tunnel View. Given the choice, I would also have referred to the location as "New Inspiration Point", and I intend to remember it as such!
[Edit] After writing this, I remembered that I have another similar photograph of the valley: "Fall Storm Over The Yosemite Valley, California" by Galen Rowell. In his write-up, Galen says "I drove to the traditional viewpoint at the Wawona Tunnel and took photographs on a tripod.... When I first projected this image for some photographer friends, one of them said it looked like a negative for Ansel Adams' famous "Clearing Winter Storm" taken in 1940 from the same location. I got out an old Hills Brothers coffee can I had saved that displayed that image as a full-size wraparound. The comparison amazed us because the values were indeed reversed. Adams had photographed a clearing winter storm after most of the snow had melted from the trees .His trees were black; mine were white. His talus slope in front of El Capitan was white; mine was black. His sky was ominous and dark, rendered through a yellow filter; mine was nearly white, because the clouds were lighter than my exposure for the ground." (Mountain Light, p. 63 - my emphasis at "from the same location"). The perspectives do appear very similar, although it is difficult to be sure since Galen's composition uses a wider angle of view than Adams'.
