In the middle section, as already stated, the Great Valley is somewhat open on the east, by reason of the small height and broad interruptions of the narrow crystalline belt; on the west it is limited by the complex series of Alleghany ridges and valleys; in the north-east section the valley is strongly enclosed on the east by the New England uplands, and on the west by the Adirondacks and Catskills (see below); in the south-west section the valley broadens from the North Carolina highlands on the south-east almost to the Cumberland plateau on the north-west, for here also the ridge-making formations weaken, although they do not entirely disappear.
Above the lake) commanding a charming view of the city, lake, the Adirondacks and the Green Mountains.
Another impressive feature of the Adirondacks is Indian Pass, a gorge about eleven miles long, between Mt.
After the continental ice sheet entirely disappeared from the state, local valley glaciers lingered in the Adirondacks and the Catskills.
In the Adirondacks are some of the best hunting and fishing grounds in the eastern United States.
From the crest of the dome of the Adirondacks proper the surface slopes in all directions to surrounding lowlands: to the St Lawrence valley on the N.; the ChamplainHudson lowland on the E.; the Mohawk valley on the S.; and Lake Ontario on the W.
It occupies the lower portion of the trough between the Adirondacks and the Green Mountains.
When the two lowlands are traced eastward they become confluent after the Niagara limestone has faded away in central New York, and the single lowland is continued under the name of Mohawk Valley, an east-west longitudinal depression that has been eroded on a belt of relatively weak strata between the resistant crystalline rocks of the Adirondacks on the north and the northern escarpment of the Appalachian plateau (Catskills-Helderbergs) on the south; forming a pathway of great historic and economic importance between the Atlantic seaports and the interior.
The rivers which most perfectly exemplify this habit are the Delaware, Susquehanna and Potomac; the Hudson, the north-eastern boundary of the middle section, is peculiar in having headwaters in the Adirondacks as well as in the Catskills (northern part of the plateau); the James, forming the south-western boundary of the section, rises in the inner valleys of the stratified belt, instead of in the plateau.
