Rock exposed during roadway construction. Several small pegmatites produced small but nice specimens of bertrandite and columbite. The bertrandite exhibits excellent crystal form, just as good as the Biermann's Quarry samples, but it does not form pseudomorphs after beryl.
Notes and specimens from the late Ronald Januzzi collection indicate there was a "anatase area" containing thin Alpine clefts in gneiss lined with albite, quartz and a few fluorite crystals (no anatase found).
