Location: Riverside County, California

Named in 1897 by USGS topographer Edmund Taylor Perkins, Jr., for Miss Marion Kelly of White Cloud, Michigan. She worked as a teacher for the Indian Bureau at the Morongo Valley Reservation and was described as "a wonderful woman, blue eyes and a gentle nature". It is told that she fell deeply in love with him, but he kept putting her off by saying that he was "married to his work". Perhaps the guilt of indecision caused him to name this summit after Marion, because when he decided to divorce his work he spurned Marion and married Jean Waters (1903). He named the adjoining summit Jean Peak after her.

Called "Marion Peak" on the original HPS Peak List.

Marion Ridge has been named recently (1967).

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

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