Leaders: Peter Thompson, Thelma Thompson, and Barry Doolan
Lithotectonic packages have been identified within the Camels Hump Group across the northern Green Mountain anticlinorium, separated by regionally extensive thrust faults: Brome-Underhill fault, Honey Hollow fault, Prospect Rock fault, and Johnson talc mine fault. Stops will be made from west to east along the Lamoille River valley to compare stratigraphy and structural style from one package to the next, and to demonstrate the timing of these faults relative to foliation, metamorphism and folding. Some stops will revisit exposures that were featured on Albee's 1972 NEIGC trip. the "Foot Brook syncline" is reinterpreted as a fault slice of Ottauquechee and Stowe correlatives thrust over Hazens Notch and Fayston rift-drift clastics, all deformed by Taconian and Acadian folds. The trip will end near the starting point of Trip B-3, which continued the transect eastwards.
