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.

The White Mountain National Forest's Land and Resource Management Plan (Forest Plan) provides standards and guidelines to ensure that rock and geologic resources are protected, and that recreational rock and mineral collecting is carried on in such a way that many people can enjoy this recreational activity into the future.
