The Rock Landing Quarry consists of two cuts on opposite sides of a hill, but within the same granite pegmatite. They appear to have been active only in the 1920s to about 1934 and though sometimes listed as being in Portland or East Hampton, they are actually in the Haddam Neck section of Haddam. The locality is most noted for its uranium minerals and columbite. They are on private property and collecting is not allowed without the owners' permission.
