The Adirondack region is the most noticeable
feature on a map of New York State. The area is sandwiched between
the St. Lawrnece Valley in the north and the Mohawk Valley in the south
and makes up a circular region with a diameter of roughly 200 km.
The Adirondacks are sometimes mistakenly included in the Appalachian system.
They are actually a separate region, but do make up a southern extension
of the Canadian Shield. The region contains 46 peaks over 1220 m
and includes the highest point in the state: Mount Marcy is 1629 m high

The region can be divided into two sections,
the Central Highlands and the Northwest Lowlands. These two areas
are separated by the Carthage-Colton Mylonite Zone. This separation
zone is a narrow band made up of intensely deformed rocks (Roecker).
