West Quarter Dome is a granodiorite dome, in the Tenaya Canyon area of Yosemite National Park. It is composed of Half Dome Granodiorite.[2]
There are two domes, West Quarter Dome and East Quarter Dome, and they are right next to each other.[3] [4] [5] [6]
Ansel Adams took a photo, Glacial Erratic on East Quarter Dome Showing Half Dome in Background, on East Quarter Dome.[7]
The Quarter Domes are a bit up Tenaya Canyon, are across from Half Dome and Clouds Rest, thus are above Yosemite Valley, quite near to Little Yosemite Valley.[8] [6]
The Quarter Domes offer rock climbing routes, though the approach is difficult.[9] [10] [11] One well-known route is The North Face, which Yvon Chouinard and Tom Frost first climbed in 1962.[12]
