Moraines of the St. Lawrence Valley

Abstract

Two marginal moraines, the Albion and the Oswego, lying near Lake Ontario and belonging to the recessional series of western New York, were traced with substantial continuity from previously determined points near Rochester to the vicinity of Watertown, and to points farther northeast, where they were lost in the Adirondack forest. Four later moraines of the same series, passing near Watertown, Philadelphia, Gouverneur, and Dekalb, respectively, were followed with some few breaks from the region of Watertown northeast toward the Champlain-St. Lawrence watershed, which passes close to the village of Churubusco. Three of them were followed across the divide and southward along the Lake Champlain slope to the hills northwest of Plattsburg. Part of a still later moraine was found on the Champlain slope. These moraines mark successive re-advance positions of the ice front as it retreated from the basin of Lake Ontario and down the St. Lawrence Valley. They cover the entire duration of Glacial Lake Iroquois and...
