Alexander Mountain is a mountain in Larimer County, Colorado named for the pioneers John and Grant Alexander. It is within a mid-elevation ponderosa pine forest in the Canyon Lakes Ranger District of the Roosevelt National Forest with mountain mahogany, skunkbrush, and gambel oak forbs. North of US Highway 34 between Loveland and Estes Park, west of Green Ridge, and east of Cedar Creek, it is recognizable by its pyramidal shaped south face. Its habitat is mesic and dry-mesic and has cliff faces which are home to rattlesnakes. Now home to the Sylvan Dale Guest Ranch, its cultural significance is the final stand in a bear hunt in the memoirs of Gerry Spence. On July 29, 2024, an unknown ignition of a hot dry remote area on the north face of the Alexander Mountain caused the Alexander Mountain Fire, receiving national attention for a rapidly accelerating wildfire causing a wide evacuation area under volatile circumstances and risking losses to communication and energy infrastructure as well as ranching and tourism communities along the Big Thompson River near Drake, Colorado.
