San Isabel National Forest

Went out for another weekend of leaf peeping and came across this on our way up to St. Elmo and Tincup.

The Alpine Tunnel is an 1800ft long railroad tunnel at an elevation of 11,523 Ft. It was the first railroad tunnel through the Continental Divide and the U.S. Forest Service says “ it remains the highest railroad tunnel and the longest narrow gauge tunnel in North America”. The rail bed up to the tunnel is now a hiking trail. The people that built this were “badass”

Scenic Log Cabin along a lake and wiith mountains in the background, caught my eye on the back way into Aspen, Colorado

Beautiful lake. Hard to get to but glad we went. There was a man fishing on the lake. Had flippers on and wading boots in a raft. You may be able to see him on the lake to the right.
