North Table Mountain is a broad mesa just north-northeast of downtown Golden on the eastern flank of Colorado’s Front Range. Preserved as open space, it is known for its nearly flat summit, created by ancient lava flows, and for its geological link to nearby South Table Mountain across Clear Creek. The mesa combines older sedimentary rocks with cliff-forming volcanic layers about 62 to 64 million years old, and it is also noted for zeolite minerals found in one flow. Today it is a popular recreation area with trails and wildlife habitat, though its history also includes a 1909 discovery of ancient human remains and a destructive 2005 wildfire.
