Standard-atmosphere estimates for the summit of Mount Marcy (5,334 ft, from the USGS grid value). Weather moves the real values a little from day to day.
- Oxygen per breath
- 82 % of sea level
- Air is still 20.9% oxygen; there is just less air.

- Home canning
- Above 1,000 ft, USDA processing times and pressure-canner pounds go up.

Sources: pressure from the U.S. Standard Atmosphere, 1976 (NOAA, NASA, USAF); boiling point from the Antoine equation for water (Lange's Handbook of Chemistry); canning thresholds from the USDA Complete Guide to Home Canning. Not medical or food-safety advice; follow the tested USDA recipe for your altitude.
Health note: the CDC says unacclimatized travelers risk altitude illness when sleeping at about 8,000 ft or higher, and sometimes lower. This page is general information, not medical advice; read the CDC guidance on high-altitude travel and talk to a clinician before a high climb.

Frequently asked questions
How tall is Mount Marcy?
Mount Marcy is 5,343 ft (1,629 m) above sea level, according to NOAA National Geodetic Survey datasheet PG2096 (mark last recovered 1975), on the NAVD 88 datum. The highest USGS 3DEP grid value near the summit is 5,334 ft.
Why does the USGS map value differ from the published height of Mount Marcy?
The USGS 3D Elevation Program stores ground elevation as a grid of cells. Each cell holds one value for its whole area, so a pointed summit is averaged with the slopes around it and the grid reads lower than a survey of the top. Here the difference is 9 ft.
Where is Mount Marcy?
Mount Marcy is in Essex County, New York, at 44.1128, -73.9237, about 12 mi from Lake Placid. It appears on the USGS Mount Marcy 7.5-minute topographic map.
How much oxygen is there at the top of Mount Marcy?
At 5,334 ft, water boils at about 202.3 °F (94.6 °C) and standard air pressure is 24.59 inHg (833 hPa), so each breath holds about 82% of the oxygen it would at sea level. The CDC says unacclimatized travelers risk altitude illness when they sleep at about 8,000 ft or higher, and sometimes lower.
What is the closest airport to Mount Marcy?
The nearest public-use airport is Marcy Fld (1I1), 10 mi away in a straight line, at 985 ft (FAA).
