The historic picnic structures and Sunrise Amphitheater were constructed by the Civilian Conservation Corps (CCC) in the 1930s, along with improvements to Flagstaff Road (image at right). Flagstaff Summit was the site of the KKK cross burning in 1922. A large wildfire burned across the summit of Flagstaff Mountain in October 1924, followed in the late 1920s by a large community effort led by Eben Fein to replant trees. Exactly 70 years later, almost to the day, Open Space & Mountain Parks conducted a 20 acre prescribed burn on the same site -- underscoring how our preception of forest fires has changed through the years.
