Canning at about 7,620 ft in Gunnison
At about 7,620 ft, Gunnison is genuinely high country for a canner: a water bath owes every recipe 15 extra minutes, and the pressure canner comes into its own — 14 lb on a dial gauge, 15 lb weighted. The label below is the whole answer.

canningdates.com — Gunnison, CO at about 7,620 ft, from the published USDA adjustment bands. Low-acid foods must be pressure canned.
Gunnison at about 7,620 ft
Gunnison holds its high sagebrush valley at about 7,620 ft, second only to Leadville among Colorado's featured towns, sitting well inside the 6,001–8,000 ft band. The winter cold here is legendary, but it's the elevation that writes your numbers.
Adjustments come in bands, not curves. The whole 6,001–8,000 ft band gets the same 15 added minutes and the same 14 lb dial setting, so the difference between your kitchen and about 7,620 ft almost never matters. Live near the top of the band and unsure which side you're on? Use the higher band — a little extra processing costs texture; too little costs safety.
As for the number itself: Gunnison's elevation was checked against the USGS elevation service, starting from the NOAA weather-station inventory (GUNNISON 3SW). Elevation shifts block to block in any town, but the bands are wide on purpose — a station a few miles out almost never changes the row.
Not your kitchen? The altitude lookup turns any ZIP or town into a card like this one. Recipe already in hand? The processing time adjuster takes your recipe's minutes and applies Gunnison's band for you.
Frequently asked questions
What changes for canning at Gunnison's elevation?
Most of the label. At about 7,620 ft — the 6,001–8,000 ft band — a water bath owes every recipe 15 extra minutes, a dial gauge runs 14 lb, and a weighted gauge 15 lb. The one thing that doesn't change is pressure-canning time, which stays exactly as tested.
Is a water bath still practical this high up?
For high-acid foods it's still safe — the published table covers Gunnison with the 15-minute addition — but that's real extra stove time on every batch. Elevations like this are where the pressure canner earns its place for foods that allow either method; for low-acid foods it was never optional anywhere.
Why does the dial read 14 lb here when my recipe says something lower?
The recipe's printed pressure assumes a kitchen near sea level. At about 7,620 ft the air above the canner pushes back less, so the gauge must read higher — 14 lb — for the inside of the canner to reach the same tested temperature. Same heat, different number on the dial.
How careful do I need to be about exact elevation in Gunnison?
Less than you'd think, and more than at lower elevations. The 6,001–8,000 ft band shares one answer, so small differences vanish — but mountain towns can genuinely straddle a band edge. If part of town sits clearly higher than about 7,620 ft, check that spot; when in doubt, the higher band is the safe read.
