Summary:

Pg. 39. For shaly phase of upper Trenton typically developed along East Canada Creek below Dolgeville, Herkimer County, Cushing, 1909 [New York State Mus. Bull., no. 126, p. 20, 21 footnote] has proposed the name Dolgeville shale. These shales were previously described by Cushing as "Trenton-Utica passage beds." In Lake Champlain region to the north and east from Plattsburg somewhat similar passage beds of uncertain stratigraphic equivalency have been mapped as Cumberland Head shale by Cushing, 1905 [New York State Mus. Bull., no. 95, p. 271-453].

Summary:

Pg. 108-116. Cumberland Head shale (Cushing 1905, pl. 13) consists of blue-black slaty limestones and calcareous shales with some firmer limestone bands. Replaces Canajoharie shale on New York side of Champlain basin. Lithologically very different from Canajoharie shale of Panton shore and southern Champlain basin in general, for prevailing element is slaty limestone and graptolite shale was not observed at all. Beds are strangely barren of fossils, but those found suggest lower and middle Trenton. Are probably in part at least = Canajoharie shale, but are lithologically and faunistically a differerent facies and deposited under different conditions if not in a separate basin, therefore deserve separate name. Overlain by Stony Point shale and underlain by Trenton limestone. [Age is Middle Ordovician.]
Named from Cumberland Head, near Plattsburg, NY.

Summary:

Geographically extended the Cumberland Head to VT and revised it to the Cumberland Head formation of the Trenton group. Reference region is South Hero Island, Grand Isle Co., VT, 2 miles southeast of Cumberland Head. Redescribed as including argillaceous limestones and limestone-bearing black shales overlying lowest Sherman Fall Shoreham limestone and underlying Stony Point black shale. Thickness is typically 150 feet.
