Pywiack Dome

Pywiack Dome is a prominent 600 foot granite dome in Yosemite National Park, located 0.7 miles north-east of Tenaya Lake, 4 miles west of Tuolumne Meadows and 200 feet from the Tioga Road. It is quite near Harlequin Dome, and North and South Whizz Domes are north.

Josiah Whitney the head of California Geological Survey wrote in 1863 about Pywiack Dome in Geology: At the head of Lake Tenaya is a very conspicuous conical knob of bare granite, about 800 feet high, the sides of which are everywhere finely polished and grooved by former glaciers.
