When I drive from Renton (Seattle area) to Moab I usually take US 6 from Spanish Fork (Utah)
to Thistle, Soldier Summit, Price and Green River. In October 2006 I tried something different:
rather than going east at Thistle on US 6 I went south to Fairview, then east to Huntington
and Price. In Fairview I set the altimeter (6033 feet or 1839 meters) so I could monitor my
elevation progress as I drove eastward on Utah Highway 31. About eight miles east of Fairview
I went over an unnamed pass whose posted elevation is 9655 feet (2943m). At the pass it was
cold and snowing. My altimeter's reading at the pass was off by 200 feet; the cold, dense
air probably forced the altimeter to register lower than expected.
