Colorado, United States
South Table Mountain is a mesa located just southeast of Golden, Colorado in Jefferson County, Colorado. Its most distinctive feature is its cap of basalt rock formed from ancient lava flows. South Table Mountain is a popular scenic and recreational destination of the Denver metro area, and most of it is preserved as Jefferson County Open Space. Its landmark prominence is Castle Rock, a small higher butte projecting from the mesa's northwest end. The mountain has a twin formation nearby, known as North Table Mountain.
