While the typically coldest locations near the Salt River were near -10F such as Double L Ranch and at the Afton airport,  other higher elevation locations near the west slopes of the Salt Range such as in Star Valley Ranch were as much as 20 degrees higher.

The recently added Star Valley Ranch weather station(Star Valley Ranch Heights) located in the forest at nearly 6700 feet elevation was some 20 degrees warmer than the coldest locations just a couple miles to the west.

However probably the most frigid area, also typical of these clear, calm nights is at the mouth of  Snake River Canyon.  The Alpine airport while still above zero has had winds up to 18 mph dropping the wind chills to 10 below. These Canyon winds originate in the Snake River Canyon, upstream from Alpine and blow downriver across Palisades reservoir, Swan Valley to Ririe. Easterly winds gusting to nearly 40 mph were observed near Antelope Flats.
