Parker Peak sits between Mount Wood and Koip Peak along the border of Yosemite National Park and the Ansel Adams Wilderness. The peak is an easy half mile scramble from Koip Peak Pass. Similar to the other peaks in the area, Parker is a scree pile of metamorphic slate.
Parker Peak (and Pass/Creek/etc) were named for an early settler of Mono County and the name dates back to at least the 1880s. (Peter Browning, Yosemite Place Names
