Map of the Adirondacks

The whole Adirondacks on real terrain, from our satellite elevation model — the full arc masked to the range’s mapped boundary, with 5 of its great peaks pinned (each labelled with its surveyed height). Mount Marcy tops them all at 5,344 ft (1,629 m). Drag to spin it (two-finger to orbit on mobile).
Where are the Adirondacks?
The Adirondacks lie entirely within the United States. The area below is this page’s own measurement — the range boundary intersected with the outline of the United States, by true (geodesic) area.
| Country | Share of range | Area |
|---|---|---|
| United States | 100.0% | 2,478 mi² (6,417 km²) |
Range boundary: GMBA Mountain Inventory v2.0 (standard extent). Country outlines: geoBoundaries ADM0. Computed range area 6,417 km² — within about 1% of GMBA’s published 6,426 km².
The highest peak: Mount Marcy
The highest point of the Adirondacks is Mount Marcy, at 5,344 ft (1,629 m) — the highest point in New York State.

Great peaks of the Adirondacks
A curated selection — the High Peaks of the Adirondacks, chosen for fame and spread rather than by a strict height cutoff. Each is pinned on the map above; the heights here are the surveyed figures.
| Peak | Elevation | Country | Note |
|---|---|---|---|
| Mount Marcyhighest | 5,344 ft (1,629 m) | Essex Co., New York | Highest point in New York State |
| Algonquin Peak | 5,115 ft (1,559 m) | Essex Co., New York | Second-highest in New York, in the MacIntyre Range |
| Mount Haystack | 4,954 ft (1,510 m) | Essex Co., New York | Third-highest, in the Great Range |
| Mount Skylight | 4,925 ft (1,501 m) | Essex Co., New York | Fourth-highest of the High Peaks |
| Whiteface Mountain | 4,865 ft (1,483 m) | Essex Co., New York | Isolated northern peak; 1980 Winter Olympics ski area |
Relief and elevation range
Across the mapped range the land runs from about 89 ft (27 m) on the valley floors to 5,279 ft (1,609 m) at the highest ground — a vertical range of 5,190 ft (1,582 m), which puts the Adirondacks in the moderate-relief class. The mean elevation is 1,877 ft (572 m) and the median 1,867 ft (569 m); the two sitting close together says the height is spread broadly across the range, not concentrated in a few peaks over otherwise low ground.
The distribution above is the share of the range’s area at each elevation, computed from the same satellite model as the maps. It reads the Adirondacks as a true massif — a large area held high — rather than a thin crest.
Adirondacks FAQ
- How many countries do the Adirondacks cross?
- The Adirondacks lie entirely within the United States — a single country.
- How were the Adirondacks formed?
- The Adirondacks are a great dome of ancient rock — a mass of billion-year-old bedrock pushed up relatively recently and still slowly rising, geologically separate from the Appalachians to the south.
- Is Mount Marcy the highest peak in the Adirondacks?
- Yes. Mount Marcy, at 5,344 ft (1,629 m), is the highest point anywhere in the Adirondacks. The next-highest of the peaks pinned here, Algonquin Peak, is about 230 ft (70 m) lower.
