St Catherine's Chapel on the Rock

My wife and I were in C0olorado for a few days in October and went up into the Rockies one of those days for some sightseeing and a drive. Following Highway 7 south we visited St. Catherine's Chapel on the Rock, a Roman Catholic chapel, open to visitors. We had failed to get into Rocky Mountain National Park since they now have a system of timed entries, and a drive south was the only alternative we could think of.
