List Description

To be on this list, a peak must be the triple divide point of three basins of rivers that reach marine water, and the smallest of these basins must be over 100 square miles. This last condition excludes what could easily be hundreds of peaks that are triple divides that involve tiny coastal creeks. Peaks located in Pennsylvania, New Jersey, New York, and the six New England states are listed.

Outside of the two major New Hampshire 4000-footers at the top of the list, most of the other peaks are quite obscure. However, the river systems that meet at these points will be familiar to most Northeast residents, and finding the hydrographic junction of three major rivers might have an intuitive appeal to many peakbaggers.
