Salmon sits at about 4,000 feet where the Lemhi River meets the Salmon River, in a narrow valley ringed by mountains. Lewis and Clark crossed into the Lemhi Valley in 1805, and Sacagawea was born near here.

High desert. Central Oregon, the high, cold valleys of eastern Oregon, and Idaho mountain towns like McCall and Salmon. Frost is possible almost any month. Use row covers, wall-o-water or cloches for warm crops, and choose short-season varieties.
Gardening in the Magic Valley and eastern Idaho. The Snake River Plain sits high, with cold nights, wind and a short season, and soils are often alkaline. Pick quick-maturing varieties and use row covers early and late in the season.
How the season in Salmon compares
With 130 frost-free days, Salmon has the 75th-longest season of the 86 Oregon, Washington and Idaho towns we cover. They run from 72 days in McCall to 330 days in Brookings and Gold Beach.
The typical last frost here, May 17, is the latest of the towns we cover in the Magic Valley and eastern Idaho: 15 days later than Pocatello and 5 days later than Rexburg.
The gap between the typical last frost and the date it's over in 9 years out of 10 is 23 days, about average for the towns on this site. Frost after the typical date still happens about half the time, so plan on covering warm crops until June 9.
Even here, sweet potatoes and pumpkins need nearly the whole season, so plant them on time and pick shorter-season varieties when you can.
For a fall and winter garden, sow carrots by July 16 and set out kale plants by July 30. Fall crops here are timed to the first frost (September 24 on average) and to shortening days.
