Daff Dome

Daff Dome or DAFF Dome is a prominent 800 feet granite dome in Yosemite National Park, 3 miles west of Tuolumne Meadows and 1,700 feet from the Tioga Road. It is southeast of Doda Dome, and is near both West Cottage Dome and East Cottage Dome; it is also near Lamb Dome. Since the dome was never officially named, the DAFF Dome name was adopted in 1960's as an acronym of "Dome Across From Fairview" Dome.
