Summary:
Named for wide occurrence on and near Camels Hump, a peak about 7 mi west of Waterbury, Washington Co., north-central VT. Consists of schist, quartzite, and gneiss. Intergrades with overlying Ottauquechee formation; unconformably overlies Precambrian interbedded gneiss, quartzite, and greenstone. Age is Cambrian.

Revised Overview	New England province

Summary:
Includes rocks previously part of the Mount Holly Complex as well as the Monastery, Granville, and Pinney Hollow formations of Osberg (1952). The Monastery, Granville, and Pinney Hollow occupy about the same stratigraphic position as the Tyson, Hoosac (or Grahamville), and Pinney Hollow formations of Thompson (IN Billings and others, 1952) and Brace (1953) in areas south of Rochester, VT. It has been possible to trace the correlation of these units northward, but none form practical mapping units in this quad because of lithologic character along strike. The Camels Hump group in this quad therefore includes a lower unnamed unit composed of albite schist and gneiss, graphitic schist and quartzite, a middle unit composed of quartz-sericite-chlorite-magnetite-albite schist, and the Belvidere Mountain amphibolite (defined by Keith, 1932) at the top of the group. Camels Hump group is also mapped undivided.

Summary:
Camels Hump group includes in this area (ascending) Pinnacle formation (Clark, 1936), Underhill formation (Christman and Secor, 1961), Mount Abraham schist (new), Hazens Notch formation (not named in this paper, see Cady and others, 1963), and Pinney Hollow formation (Perry, 1929). Age revised as Cambrian(?) and Early Cambrian. Pinnacle, Underhill, Mount Abraham and lower part of Hazens Notch formations are considered Cambrian(?) because, to the north in southern Quebec, section with Pinnacle at its base includes more than 1,000 ft of strata conformably beneath fossiliferous Lower Cambrian rocks (Clark, 1936). Uppermost part of Hazens Notch and Pinney Hollow formations are Early Cambrian because the Pinney Hollow is beneath and grades up into Ottauquechee formation, which correlates stratigraphically with fossiliferous Middle Cambrian strata west of Green Mountain anticlinorium in northwestern VT (Cady, 1960).
