The dol. boulders of all sizes up to & feet long, angular or subangular. Between the layer beds are the thin bedded blue li. all cemented by dol. The material is either fine-grained.

The blue thin-bedded li. looking across the river one sees two other layer holders up to 6 yards high. Heavy redded blue-grey dol. in 5 or 6 beds, 15 feet. Occasionally there is a coarse purdle of the bedded li. in places with much intruf cong, and some boulders up to 12mths across.

Looking across the river one sees this same deposit opposite the power house. It seems to be from 10 to 15 feet thick. This is the last of the Milton series, The comes in the Highgate series.
