Schooner (1958) describes it as "an old rock cut on Route 2 near the Glastonbury-Marlborough line...in the latter town". Because the current State Route 2 expressway was under construction in the late 1950s in this area, Schooner's use of "old" in 1958 means this was a cut on the old Route 2, aka the New London Turnpike from Hartford. The current expressway bypasses much of this older route, but this locality is at an area where the expressway snakes through a pass in rugged terrain formed by the Devonian-Silurian Fitch, Clough and Littleton metasediments. Here the old turnpike, and most likely the locality also, was obliterated by the new overlapping expressway constructed through the same pass. It could be they were exploring rock opened by the new Route 2 construction. He attributes the discovery of what appears to be an alpine cleft type occurrence to himself and Klaus Albrecht.

In Schooner (1961) he provides further details on the occurrence:
"which lined an open cavity in pegmatized gneiss, near a small lens of metamorphosed limestone". This statement, and the presence of calc-silicate minerals in the cavity, suggests the cut was in the Fitch Formation - a calc-silicate gneiss with minor marble.

Because the exact locality is not known, the locality coordinates are based on the presence of Rt. 2 expressway cuts visible on USGS topo maps and where the Fitch Formation crosses the road.
