On the Telluride side is the remains of an old mining Town, not camp, but a true town.  This town, called Tom Boy once had over 900 residents, complete with tennis courts.  The town closed in 1927 when the ore at the Tom boy mine ran out.

(This is the remains of the Bullion Tunnel Mine–on your way into Tomboy from the Telluride side)

You can only reach this site, about 2 -3 months out of the year, the rest of the time the road is closed because of weather.

This looks like it might have been a rooming house or hotel.

Just for the record Imogene Pass is rated a 4 out of the possible 5 as far as 4-wheel drive difficulty and is the second highest pass in Colorado.

Whenever I see old mining towns, camps and mines in these hills mountains I am reminded once more….living here is not for the faint hearted.
