(27) Sep. 28-1924 Sunday Left Barre, VT at 9 A.M! The light gray granite here is of Post-Ordovician age since it cuts known Ordovician strata. At 2 miles S.E. of Barre are std. to look at the high metamorphosed slates that have furnished Richards on peptolites. It is favored material or common in slates. At about 3 miles S.E. of Barre we see one of the thicker piles of boulder clay anywhere, it is at least 100 feet thick down to the streambed. Keith tells me that the area of the Green and White Mts is a thrice elevated foreplain, uplifted during the Cengric. Our route yesterday was up of the Drimoorsti and today down the Pratt River.
