Pawnee - Buchanan Loop, Colorado

The Pawnee Pass (12,541') - Buchanan Pass (11,837') Loop is a terrific, tough and super scenic 26-mile route in Colorado's Indian Peaks Wilderness Here is a nice trip report on the route from Charles Danforth (from which I took the map and photo). More photos are here

I am not aware of the FKT for this route. It has been done by many local runners, but I haven't heard of a particularly fast time yet. I include the route here because it is a true classic and has been done a lot.
