Location: Los Angeles County, California
Named in 1920 by USFS surveyor Don McLain for J. L. Mooney, a young Forest Ranger and telephone lineman who was killed in France during WWI The USBGN (citing Erwin G. Gudde) believes it to be "John". [It is this researcher's observation that when Gudde is short of facts he tends to find the temptation to fabricate them irresistible.] John W. Robinson learned from McLain that his first name was actually "Joseph".
Name first appears on USFS Angeles National Forest map (1925).
Name officially accepted by USBGN (1932).
Peak was on the original 1946 HPS Peak List.
Weldon Heald climbed this peak in 1941.
