Location: Riverside County, California

Named in 1897 by USGS topographer Edmund Taylor Perkins, Jr, for his sweetheart Jean Waters of Plumas County, whom he had met earlier while working in northern California. They were married in 1903, despite the fact that he also named an adjoining summit after another girl fiend named Marion.

Name first appears on USGS San Jacinto topo (1901).

Peak was on the original 1946 HPS Peak List. Weldon Heald climbed this peak in 1942.
