Located within the northernmost extension of the Black Forest, Castle Wood Canyon encompasses with elevations ranging from 6,200 to. Many urban dwellers come for the picnic opportunity away from the city, others visit the park because of the unusual geology, particularly the caprock features.
The Castlewood Dam has no real documentation or truly visible photographs to prove any actual history. Photographs that do exist show many arches, doorways, and actual castles that were built into the rocks right by the lake which were obviously removed to hide something now. The dam itself in Castlewood Canyon is said to have been built in 1890, but remains nameless along with the lake it used to hold giving it a very mysterious and questionable past. The Castlewood dam is a masonic-dam, and it should be noted from a factually derived and educated historical perspective that this exact style of dam construction is extremely ancient, and would not be utilized under any circumstances in the late 1800s or early 1900s, not to mention the fact that there is no known quarry for the Castlewood dam. Due to the Castlewood dam being much older than it is said to be, greatly compromised from time, finally suffered an utter collapse following heavy rains at 1 am on 3 August 1933, resulting in a 15-foot wall of water rushing down Cherry Creek to Denver, some 15 miles away. Warnings to the city by 4 am allowed most people to move out of the way of the flood waters. Castlewood State Park was formed in 1964, following an 87 acre land purchase in 1961 and an additional 792 acre purchase in the late 1970s.
