Excerpt from The Paleozoic Stratigraphy of New York The route back to Albany follows the shore line of glacial Lake Iroquois for some distance, then crosses the belt of Medina rocks to Rochester. Here is seen the gorge of the lower Genesee River, with its section of the early Silurian beds. Remarkable glacial features are displayed along the route lead ing east to Syracuse. The Salina beds, which inclose valuable salt and gypsum deposits, are encountered on this stretch. The Clinton beds are found in their full development between Syracuse and Utica, where a detour is made to Trenton Falls, one of the historic localities for New York geology. Thence the way leads down the Mohawk Valley, affording a section from the Potsdam to the Frankfort, with another detour north to Sara toga Springs, over the Adirondack pre-cambrian formations for some distance, and into Albany.

Excerpt from Eastern New York and Western New England The route to be followed in excursion A - l is indicated on Figure 1. In the Hudson Valley the Paleozoic stratigraphy will be reviewed briefly, and evidence of two notable disturbances will be examined. In the Adirondack Mountains the results of recent field studies will be used in considering the form of the great anorthosite mass, the mechanics of its intrusion, and the differentiation of the magma into various rock types. The complex belt of folds, thrusts, and schistosity in western Vermont and Massachusetts still holds numerous major problems of stratigraphy and structure; these will be pointed out during examination of the results of recent detailed work. Old erosion surfaces are particularly well displayed in western New England. They will be pointed out, and their bearing on the late geologic history will be discussed. In the Connecticut Valley the com position, structure, and fossil content of the Triassic rocks will be studied, and the problem of the original extent of the Triassic strata will be considered. In this area features that prove widespread stagnation of the last ice sheet are especially well developed. Several museums in the region have rich paleontologic and geologic collections, which will be utilized to supplement the field examinations.
