Observation Peak is a 12,362-foot-elevation (3,768 meter) summit located in Fresno County, California, United States.

The first ascent of the summit was made July 25, 1902, by Joseph Nisbet LeConte and Curtis W. Lindley via Dumbbell Lakes.

[6][7] This mountain's toponym has been officially adopted by the United States Board on Geographic Names.

[8] Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains.

As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snowfall onto the range.
