Where to Find Feldspar in Maine
Maine feldspar is a defining mineral of the state's pegmatite belt. Mount Apatite in Auburn (Androscoggin County) yields cleavelandite (white tabular albite) alongside green and watermelon tourmaline. Mount Mica in Paris (Oxford County) produces microcline, perthite, and amazonite (the blue-green potassium feldspar) in some of the largest pegmatite pockets in North America. The Newry pegmatites add cleavelandite blocks and amazonite, and the Bumpus quarry has produced perthite up to several meters across. Most Maine feldspar is collected from quarry dumps; specimen-grade crystals come from active pocket mining and rarely surface on the open dumps.

Standout feldspar spots in Maine
Hand-picked from the full list below, with the reason each one earns a trip.
Tunk Mountain
Hancock County County
Tunk Mountain is carved from the Tunk Lake pluton, a concentrically zoned alkali granite that grades into rapakivi granite, producing smoky quartz, perthitic feldspar, and dark hornblende-bearing rock. The peak sits on Donnell Pond Public Reserved Land, where the Maine Geological Survey allows casual hobby collecting without a permit. It is a granite-and-quartz site rather than a gem pegmatite.
Edgecomb Quarry (Schmid Preserve)
Lincoln County County
The Edgecomb pegmatite pits sit inside the 766-acre Schmid Preserve, town land laced with more than seven miles of public trails, where 1880s feldspar and mica workings exposed almandine garnet, beryl, and aquamarine. The preserve is free and open to the public. Smoky quartz and muscovite occur in the same pegmatite.
Deer Hill (White Mountain National Forest)
Oxford County County
Deer Hill is a US Forest Service designated mineral collecting area in the White Mountain National Forest, known for amethyst recovered by screening the sandy soil. Feldspar, beryl, garnet, columbite, and pyrite are also documented at the site. Hobby collecting is allowed under a no-fee day permit.
Lord Hill (White Mountain National Forest)
Oxford County County
Lord Hill is a granite pegmatite in the White Mountain National Forest where more than 50 minerals have been recorded, most famously large white topaz and smoky quartz crystals encrusted with rare phenakite. The US Forest Service runs it as a designated collecting area open under a no-fee day permit. Feldspar and garnet round out the finds.
