These mountains are Mt. Princeton on the right and Mt. Antero on the left, Antero is slightly taller than Princeton. I have been on top of Antero twice in the 70's. I don't think I could make it up there again. This shot was from the highway between Buena Vista and Salida, CO.  Yes I did make it to Buena Vista today.  My wife and I made a trip out west in 2013 in September and spent 3 days in the area.
