Rossville Road Cut

The Rossville Road Cut is a well-known, small copper-mineral locality on an unnumbered road between Rossville and Dillsburg in Warrington Township, York County, Pennsylvania — a road cut exposed by highway work in 1974 that's been a regular stop for Pennsylvania collectors ever since. The draw is azurite and malachite: blue and green copper carbonate coatings formed where near-surface groundwater converted copper sulfides (originally deposited by hydrothermal fluids around a crystallizing diabase intrusion) into the colorful secondary minerals collectors actually want. It's a genuinely public spot — a highway cut, not private property — but decades of collecting have pushed the productive face back into the bank, so getting anything now takes real hammer work, not surface picking.

The road cut is on an unnumbered road connecting Rossville to Dillsburg through Stevenstown, about 0.7 mile northwest of Rossville off Route 177, in Warrington Township, York County, Pennsylvania.

Hard-rock work with a hammer and chisel — the accessible face has been worked back roughly 3 feet into the cut over the years, so this isn't surface picking anymore. Wear eye protection. Collectors describe the cut itself as unstable/unsafe in places; be cautious about undercutting the bank, and watch for traffic since you're working right along a road shoulder.

This is a Pennsylvania state road cut — public right-of-way, not private property, and no fee or permission is documented as required. That said, road-cut collecting always carries traffic and rockfall risk; park well clear of the travel lane and don't work directly above other collectors. No official state geological survey page was found addressing this specific cut, so treat collector trip reports as the best available source on current conditions.
