A former Fe mine located 2.3 km (1.4 miles) WNW of Cumberland and 4.8 km (3.0 miles) E of Woonsocket.

Type locality for cumberlandite (titaniferous magnetite melatroctolite).
Intruded into the Late Proterozoic Blackstone Group between 620 and 370 mya. Formed by gravitational settling of olivine, titaniferous magnetite and cumulophyric plagioclase-olivine aggregates from an anorthositic gabbro magma. A good view of the parent gabbro can be seen at http://www.mindat.org/loc-27231.html.

Ore from this locality was mined as early as 1703, and mixed with hematite from Cranston, RI, probably in a foundry in Cumberland RI (Singewald, 1913).
