There is a formation of the earth here in Creede, Colorado, where we now are, called the Wagon Wheel Gap. Before they found the easier way, this was the way into town back in the mining era. Now about 400 folks, Creede was the last of Colorado's silver loads and once had a population of 10,000. It is a fine part of the Rockies and our last stand before we head into Kansas and on to places east in a couple of weeks.
Here is the top of the gap.
