Pg. 69-70. Eddy Hill grit. [Replaces †Black Patch grit of T.N. Dale (1893).] Consists of 10 to 40 feet of dark gray grit or sandstone with black shaly patches, sometimes with calcareous nodules. Underlies the Schodack shales and limestones and overlies the Mettawee slate; all Lower Cambrian.
Named for exposures at Eddy Hill, near Fair Haven, Rutland Co., VT. [Eddy Hill is probably in Whitehall quadrangle, but name does not appear on that map. It may be unnamed hill just southeast of Fair Haven.] Recognized in Washington Co., eastern NY, and Rutland Co., southwestern VT.

Pg. 34-35. [†Eddy Hill Grit abandoned.] The bulk of the Eddy Hill, including the type outcrop, is relegated to Mudd Pond Quartzite Member of Bull Formation (Zen, 1961, p. 303); some outcrops called Eddy Hill by Fowler are now mapped as part of the West Castleton Formation (Zen, 1961, p. 305).
