Gibraltar Mountain, elevation 3,784 ft (1,153 m), is a peak in the Monashee Mountains, located 1.5 mi (2.4 km) southeast of Republic, Washington, United States. The name was originally spelled with an "e" as Gibralter Mountain, but current sources use an "a" instead. The main geologic mass of the mountain is composed of Sanpoil Volcanics igneous rock, while topographically, it is defined by several faults, an ancient river system, and the Cordilleran ice sheet. A diverse group of plants is found across the mountain slopes, including trees, shrubs, herbs and parasitic. Wildfires are a threat to the mountain with areas being high risk due to wildland–urban interface and proximity to Republic. Human use has included scouting and trail building.
