      Glen Canyon Park is a 66.6-acre recreation area located off of Elk Street and O'Shaughessy Boulevards in the Glen Park District. Rich with a history that spans back to the 1850s, Glen Canyon Park has seen a myriad of uses ranging from Adolph Sutro's personal "Gum Tree Ranch"; to the Crocker Real Estate Company's mini-amusement park and picnic site; to an earthquake refugee camp. Not until 1992 did the park come into its current state as an official public recreation site operated and maintained by the San Francisco Recreation and Parks Department. The canyon itself, one of the City's "Significant Natural Resource Areas", has naturally forested slopes, native chert outcroppings, and wild flower growths including important native San Francisco species.
