'''Monrovia Peak''' is a {{convert|5,412|ft|meter|adj=mid|-elevation|abbr=off|sp=us}} mountain summit located in the San Gabriel Mountains, in Los Angeles County, California, United States.

==Description== Monrovia Peak is set within San Gabriel Mountains National Monument, approximately {{convert|4|mi|km|spell=in}} northeast of the community of Monrovia and {{convert|20.|mi|km}} northeast of downtown Los Angeles. The May 2, 2024, expansion of the San Gabriel Mountains National Monument by President Biden brought Monrovia Peak within the boundary of the monument.<ref name=USFS/> Topographic relief is significant as the summit rises over {{convert|1800.|ft|m|abbr=off|sp=us}} above Cold Springs Canyon in approximately one mile. Reaching the summit involves 12 miles of hiking with 5,300 feet of elevation gain.<ref name=hps/> This mountain's toponym has been officially adopted by the U.S. Board on Geographic Names,<ref name="gnis"/> and it is named in association with the city of Monrovia, of which William N. Monroe (1841–1935) is Monrovia's eponym.<ref name=hps2>[https://hundredpeaks.org/signatures/15a.htm ''15A Monrovia Peak''], Hundred Peaks Section, Sierra Club, Retrieved 2024-05-24.</ref>

==Climate== According to the Köppen climate classification system, Monrovia Peak is located in a continental climate zone (Dsa) with mostly dry summers (except for scattered summer thunderstorms) and cold, wet winters.<ref name=peakvisor2>{{cite web|url=https://peakvisor.com/range/san-gabriel-mountains.html|title=San Gabriel Mountains, Peakvisor.com|access-date=2024-05-22}}</ref> Most weather fronts originating in the Pacific Ocean travel east toward the San Gabriel Mountains. As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture onto the range. Precipitation runoff from this mountain drains into the San Gabriel River watershed.
