Location: Los Angeles County, California
Name derived from the nearby suburban town of Monrovia which itself was not named (as is often presumed) for the U.S. President, but rather for William N. Monroe (1841-1935) a railroad construction engineer. He headed a group of associates who laid out the town of Monrovia on sixty acres of Ranchos Santa Anita and Azusa de Duarte (1886).
Gudde only adds that "the form of the place name reflects Monrovia in Liberia", named "after [5th US] President [James] Monroe [1758-1831) in a Latinizing period.".
Name first appears on USGS Pomona topo (1904).
Peak was on the original 1946 HPS Peak List.
Weldon Heald climbed this peak in 1939.
