Climbing.
The west face of the formation is popular with rock climbers and has several multi-pitch slab climbs easily visible from the Tioga Road. Earliest was "Dike Route" a 6 pitch YDS 5.9R first climbed in August 1966 by Tom Gerughty, Roger Evje and Dave Meeks. Other popular climbs include Zee Tree (a 5 pitch YDS 5.7) and Aqua Knobby (a 4 pitch YDS 5.9)
Etymology.
"Py-we-ack" in the native language means "glistening rocks", and the native people applied it to both the Tenaya Creek and Tenaya Lake, due to the abundance of glacial polish in the upper Tenaya basin. In 1932 the name "Pywiack" has applied to Pywiack Cascade. Pywiack Dome was known early by various names, including "Murphy's Dome", "Teapot Dome", "Matthes Dome", "Ten-ieya Dome", and "Turtle Rock". The name "Pywiack Dome" was recommended by David Brower in the early 1950s, and first appeared on the 1956 15-minute quadrangle map.
