About this location

Dollyhyde Creek takes its name from the historic Dolyhyde Mine (also spelled Dolly Hyde Mine), a small copper-lead-zinc operation south of Libertytown in Frederick County, Maryland.[1] It was one of three related mines in the Linganore Mining District worked in the mid-1800s — Dollyhyde itself, plus nearby Liberty and New London — with sporadic reopening attempts through the 1950s.[1][2] Copper was a secondary product here, not the main draw; this was primarily a lead-zinc prospect. The specimen list attached to this location (bornite, pink calcite, covellite, malachite, quartz) is consistent with a small copper-sulfide skarn/vein system like this one, though it's not independently confirmed mineral-by-mineral from a current source. This is old, small-scale 19th-century workings on what is almost certainly private farmland today — not a maintained public site.

Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.

Found Here

Copper secondary minerals typical of a weathered sulfide deposit: malachite (green copper carbonate) and bornite/covellite as tarnished sulfide ore, with quartz and pink calcite as gangue. This mineral suite matches the deposit type documented for the Dolyhyde/Liberty mines (copper as a tertiary commodity alongside lead and zinc) but the specific list has not been verified against a current mineralogical source for this exact locality.[1]

Getting there

Dollyhyde Road runs through Libertytown, Frederick County, Maryland, in the Piedmont Upland region.[1] No trailhead, parking area, or public access point is documented — this reads as rural farm country, and any historic shaft or adit locations would need to be pinpointed against current property lines.

Collecting here

UNVERIFIED. If any surface material remains on old dumps, it would be hand-tool surface collecting (hammer, no digging equipment needed for float). No current operator or access program is documented.

Know before you go

This is private land in the Piedmont farm belt of Frederick County — there is no indication of public ownership or an organized collecting program at Dollyhyde Creek. The historic mine was worked from 1839 into the 1850s with intermittent reopening attempts as late as the 1950s, but nothing suggests current legal public access.[1] Contact Frederick County or check current parcel ownership before attempting to visit; do not cross private land without permission.
