From the author’s notes:
The Dawson Butte quadrangle, Colorado, is located in Douglas County, on the eastern margin of the Colorado Front Range. The town of Castle Rock (2002 population 29,000) is located less than ¼-mile from the northeastern boundary of the quadrangle, along Interstate 25. West Plum Creek and East Plum Creek, the major drainages in the quadrangle, flow northward to Sedalia where they join to form Plum Creek. The highest point on the quadrangle is Dawson Butte (elevation 7,460 feet), and the lowest point (elevation 5,920 feet) is the West Plum Creek valley bottom in the northwestern part of the quadrangle.
