Johnson Peak is made of eroded granite. At 85 Ma, the Johnson Granite Porphyry is the youngest granite rock in the Yosemite National Park, though the entire peak formed beneath the Earth's crust. It broached the surface much later, via subduction.[3]
The name, and the mountain range
R.B. Marshall named Johnson Peak, in the 1890s, to honor a teamster and guide in his survey party, with Professor Davidson. They also climbed Mount Conness.[3]
Johnson Peak is part of the Cathedral Range.[4]
Geology, and the area
Johnson granite porphyry, whose name derives from Johnson Peak, is found there.[5] Far above what is now Johnson Peak, it is possible that a volcanic caldera once may have existed.[6][7]
Johnson Peak is quite near Elizabeth Lake.[8]
