This map shows the locations of campsites on the St. Lawerence Flat Lands and surrounding areas in the north-western Adirondacks. I believe this is a fairly complete map for state land up that way, please see individual state forests for details.
The first wilderness part of the Northville Placid Trail is remarkably steep for this part of Adirondacks, climbing 700 feet over a ridge on the first mile, then dropping down 100 feet to Mud Lake over a half mile, then over the next four miles you lose about 550 feet elevation until you reach West Stoney Creek and the lean-to.

The Upper Hudson Ski Loop trail is 4.2 miles and parallels the Goodnow River (north-side) to the Hudson River. The trail heads north along the Hudson for a short distance before looping back and reconnecting with itself 0.5 mile from the trailhead
