A small, unusual pegmatite cropping out at what Schooner (1958) (the reported discoverer in 1938 - see Zodac (1940)), called the "Second Long Railroad Cut East of East Hampton" and what Weber and Sullivan (1995) called the "Linkpot railroad cut". It is along the former Airline Railroad trail and is reached by heading east from the parking area at the end of Smith Street. Schooner, in Zodac (1940) says that "The chlorophane occurs as a small vein, 1 inch wide, in a 2-foot pegmatite dike, 8 ft. off the ground and about 50 ft. from the beginning [west end] of the cut." The trail is now State of Connecticut land and collecting is not allowed without a permit from the Dept. of Energy & Environmental Protection.

The association of allanite-(Ce), bastnaesite-(Ce), fluorite, chalcopyrite, pyrite, plagioclase, and quartz makes it unusual for the Middletown pegmatite district.

Installation of an underground sewer line along the path unearthed additional minerals such as scheelite.
