Ragged Jack Mountain

Ragged Jack Mountain sits in the town of Hartford, in Maine's Oxford County pegmatite belt — the same mineral-rich corridor that includes Mount Mica and Newry. A granite pegmatite dike, roughly 2 to 5 meters thick, is exposed on a southwest-facing cliff here. Around 1910 the site produced high-quality chrysoberyl crystals, and for years collectors kept the location quiet, sometimes attributing finds to nearby Black Mountain in Peru, Maine, instead. The locality's older local name is "Ragged Ass Jack Mountain" — it was never put on USGS topographic maps under that name because of an effort to sanitize it. This is a real, historically significant pegmatite pocket, not a roadside curiosity, but it's also obscure enough that current land status and any collecting arrangement need to be confirmed before a trip.

Ragged Jack Mountain is in Hartford, Oxford County, Maine, in the general Rumford/Sumner/Peru area of the Oxford Pegmatite Field. UNVERIFIED: no specific trailhead, parking area, or public road access was confirmed in research for this dossier — treat any directions found elsewhere as unverified until confirmed with a current map or local source.

The pegmatite is exposed as a cliff face, with productive material historically coming from pegmatite boulders that had already broken off at the base rather than from digging into the dike itself. That points to surface/talus collecting as the realistic method here rather than hard-rock quarrying. General-area inference: like most Oxford County pegmatite sites, expect hand tools (rock hammer, chisel), sturdy boots for talus, and a helmet given the cliff exposure above the boulder field.

Land status at Ragged Jack Mountain is UNVERIFIED — research for this dossier did not turn up a current land manager, public-access designation, or permission requirement. Maine's general rule applies broadly: private property must be respected and owner's permission obtained before entering a collecting site (Maine Geological Survey). Given the site's rural, off-the-grid character, assume it may be private timberland unless you confirm otherwise locally. Do not rely on this dossier alone to establish legal access — verify ownership and permission before visiting.
