The High Peaks are the 46 peaks in Adirondack Mountains of New York that had all been surveyed to be over 4000 feet in elevation. Later surveys using new technology revealed four of the peaks to be slightly less than 4000 feet high, and one other peak (McNaughton) that was not part of the 46 High Peaks to actually be 4000 feet tall.

I have included GPS coordinates for the peaks, as well as some of the trailheads. I have tried make them accurate, but mistakes happen. If any of the info is wrong, please let me know.
