The Town of Warwick, New York, covers approximately 104 sq. miles. Edenville, along with Amity, is among many unincorporated areas within the town. Edenville is approximately 2 miles east of Amity and these locality designations represent essentially the same area. The co-ordinates given are for the village of Edenville itself, but all of the localities are on a ridge to the west. Virtually all the minerals listed for the Amity – Edenville area occur in the Franklin Marble. Amity is near the center of the marble outcrop belt but Edenville proper is actually east of Amity in country mostly underlain by Paleozoic dolomites and slate. Specimens simply labeled "Edenville" historically are either glacially transported boulders or were found in place on what the local collectors call "Edenite Hill" (q.v.). These localities are near the northern terminus of the Precambrian Franklin Marble Belt.

Historical locality data put on old lables depended on how the collector approached the area. If one came from the Franklin, NJ area there was probably a tendency to arrive at Amity first. If one came by way of the Village of Warwick the route to the collecting area may have passed through Edenville.

This area has attracted collectors since the early 19th century. Since the landscape is generally gentle and outcrops are small and scattered it was originally a “stone wall fence” locality, but several specific collecting pits are known. A few outcrops that yielded unusual mineral assemblages, such as large spinels, were thoroughly excavated with black powder. In the present era the area is gradually suburbanizing and so exposures are occasionally available in the foundation excavations for the new "McMansions". Development has also made access to historical localities difficult and much of Edenite Hill is under development.
