Ryerson Hill Mines

Ryerson Hill mine

The walk is moderate but short in length from Ryerson Hill Road.
     The pegmatite quarry was recently worked and there are forty-five recorded mineral species. Among the minerals found here are albite, almandine, beryl, columbite, eosphorite, fluorapatite, hydroxyl-hererite, muscovite, pyrite, quartz.
Ryerson Hill is a granite pegmatite. It was searched for good quality feldspar and mica in the era when there was a high demand for those minerals. There are many test pits in the area for this reason.

The main quarries were recently worked by Dick Dionne and he recorded forty-five different minerals.  Ryerson Hill is well known for its micro crystals of rare phosphate species associated with triphylite. Maine Mineral Adventures hopes to uncover more amazing specimens in the future. Ryerson Hill is a granite pegmatite.
