The bedrock of the White Mountains is mostly composed of igneous and metamorphic rocks, with numerous intrusions and contact zones between different rock types. From the Conway granite of the White Mountain batholith to the thick deposits of the Moat Mountain volcanic rocks, all overlain by glacial tills, this geology has resulted in diverse but limited mineral deposits in various locations across the Forest.

Gold Panning

Gold panning on the White Mountain National Forest is a recreational activity that occurs mainly on the Pemigewasset Ranger District on the west side of the White Mountain National Forest. Gold is associated with a wide variety of rock types (granitic and volcanic rocks in particular) and sediment types (stream gravels and stratified glacial material). There is a history of gold recovery in the Ammonoosuc River basin, in particular the Wild Ammonoosuc River and Tunnel Brook.
