Rifle Sight Notch - Rollins Pass Colorado 

The railroad over Rollins Pass was originally the Denver, Northwestern and Pacific Railroad, financed and built by David Moffat. It later became the Denver and Salt Lake Railroad, which was acquired by the Denver and Rio Grande Western Railroad in 1947. Use of Rollins Pass was discontinued following completion of the Moffat Tunnel in 1928.

Hello from Kansas 🇺🇸

Might be interesting if you just allowed a tiny bit of time to look around and enjoy the view. So you can fly a drone? Ok.....

Denver & Rio Grande Western Railroad never went over Rollins pass.
