Pennsylvania
Mine, Peru Creek Watershed, Summit County, Colorado
The Pennsylvania Mine produced silver, gold,
copper, lead, and zinc from 1870 into the 1900s. Acidic, metal-laden
water coming from the mine adit flows into Peru Creek. An effort to
passively treat the mine water in the early 1990s was stymied by a Clean
Water Act requirement that the organizations designing the treatment
assume liability for the abandoned mine.

Directions
From the Boulder area, take I-70 west to the
Dillon/Silverthorn exit (for Keystone Ski Area). At the base of the
exit ramp, turn right on Rt. 6 and continue through Dillon and past Dillon
Reservoir toward Keystone. As you approach Keystone, follow the
directions on the maps to the right.
The Penn Mine is readily accessible with a
4wd vehicle in good weather. An all-wheel drive vehicle with fair
ground clearance will be challenged by a short section of washed-out
road. A 2wd vehicle is not recommended.
