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.
