Mount Dana - 7/9/2005
I hiked down to Tioga Lake (9638') from the Glacier Canyon Trailhead (~9760') then up Glacier Canyon to Dana Glacier (~11320'). I put on my ski boots and crampons, took out my ice axe and climbed Dana Couloir to the east ridge and up to the summit (13057'). I was able to ski from about 10 feet from the summit down the east ridge and Dana Couloir past Dana Glacier into Glacier Canyon to about 11040'. The east ridge probably doesn't exceed 30 degrees. Dana Couloir maintains a nearly 40 degree slope for 1200 feet and is at least 60 feet wide. The snow on the east ridge and in Dana Couloir was great; no runnels, snowcups, rocks or dirt! There is a high rock wall on the east side of the couloir that allows the climber and skier to choose his or her snow firmness by how far east or west in the wide couloir they choose to travel. This is not a technically demanding summer ski, but provided excellent snow conditions. Where else in CA can one ski nearly from the summit for over 2000 feet in July? Thanks to John Minier for the suggestion.

The summit is in the center of the photo. The east ridge goes from the summit to the left (east) to the top of Dana Couloir on the left. Note that the couloir is shaded due to the high rock wall on the the left (east) side of the couloir.
Summer conditions; saw loose avalanches.
