50-60 miles to the west of Denver CO there is an interesting area in the high mountains. Two complexes of Climax molybdenum mines.
By Berthoud Pass.
Mine #1 Henderson tailing ponds.
Ore processing plant.
Second mine is located couple dozen miles to the southwest. Very picturesque area between them. Dillon reservoir.
Keep climbing toward Fremont Pass.
Beautiful ski area to your right. High country.
