Tenaya Canyon in the context of Three Chute Falls

The Pywiack Cascade is a waterfall in Yosemite National Park within the U.S. state of California. It is located a few miles downstream from the outlet of Tenaya Lake on Tenaya Creek at the head of the steep and rugged granite gorge, Tenaya Canyon. The waterfall can be viewed from Glacier Point, or by a 6-mile (9.7 km) hike from Olmsted Point, but the canyon is dangerous and the waterfall is unsafe to be reached on foot. The waterfall is highly seasonal. It typically rages in the spring and early summer while shrinking to a trickle by late summer to mid-autumn.

The water of the Pywiack Cascade slides down a steep angle of solid granite, for a total of about 600 feet (180 m). A small waterfall lies directly below the main drop. Below that, the creek continues over jumbled talus for less than a quarter of a mile (0.4 km) before it plunges over another large waterfall. Not much farther downstream is Three Chute Falls whose waters continue on into Mirror Lake and then finally empty into the Merced River, within Yosemite Valley.

Olmsted Point is a viewing area off Tioga Pass Road in Yosemite National Park which offers a view south into Tenaya Canyon, giving, in particular, a view of the northern side of Half Dome, Clouds Rest, and a view of Tenaya Lake to the east. The granite slopes immediately south and southwest of the parking lot feature numerous glacial erratics scattered about, as well as a short 0.125 mi (0.2 km) trail leading south - through a small grove of trees - to the top of a small granite dome where the view of Clouds Rest and Half Dome is clearest.

The site is named after landscape architects Frederick Law Olmsted and Frederick Law Olmsted Jr.

Mirror Lake is a small, seasonal lake located on Tenaya Creek in Yosemite National Park. Situated in Tenaya Canyon directly between North Dome and Half Dome, it is the last remnant of a large glacial lake that once filled most of Yosemite Valley at the end of the last Ice Age, and is close to disappearing due to sediment accumulation.

West Quarter Dome is a granodiorite dome, in the Tenaya Canyon area of Yosemite National Park. It is composed of Half Dome Granodiorite.

There are two domes, West Quarter Dome and East Quarter Dome, and they are right next to each other.
