From former forts and mines to log cabins and cliff dwellings, pieces of Colorado's historical past still exist around the state. Sometimes these sites are prominent and easy to spot. Other times, you have to search a little deeper to find them.

For example, a significant point of interest with a unique history sits high up at 7,600 feet in Jefferson County -  out of sight except for those willing to hike or bike up a mountain to get to it.
