The Dillon Pinnacles were formed from volcanic activity millions of years ago. Everyone I've talked to about them has said that they would be crap to climb on. I finally checked them out myself, and they are no worse then the Fishers. Pony up people! The Dillon Pinnacles seem to offer tons of free climbing objectives on spires.
I will update this more as the summer goes on and more routes go up. Many of these must have been climbed before. If you have any information about the climbing history of the Dillon Pinnacles, I would love to hear it.
Getting There
Drive about 20 miles west from Gunnison on US Hwy 50. There is a sign, bathroom and parking lot for the Dillon Pinnacles on the north side of the bridge. Walk down the side road for about 100 yard and then follow the obvious trail on your right.
