Ultramafic tectonic deposit, mined for asbestos, beginning in 1899. The excavations for this asbestos deposit are virtually continuous and overlapping. Many collectors maintain a distinction without a difference as to the names of particular pits. Although there are historical references to particular sub-locations such as the C Pit, etc., specimens from these locations have been distributed without specific labels to identify which pit or exact spot they have come from. The largest two levels are at the north end of the excavations and, consequently, which have produced most of the specimens, and are largely in Lowell, but exceptional specimens have also been found in Eden on the southern end of the quarry area. (Have fun figuring out how to label specimens from this area!)
