AIR MAIL

Where today’s air came from

The air arriving over Mountain City about 5,000 feet above the ground was over the open Pacific three days ago, and over the northern Plains a day ago, about 3,070 miles back along its path. It came down from about 13,700 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the open Pacific. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK, SIX YEARS AGO Nov. 11–12, 2020

The wettest two days this week has seen

3.00 inches of rain fell in two days, the most for this week of the year since records began in 1956. The next wettest, 1.78 inches, fell in 2002.

What Mountain City stands on

Mountain City’s center stands about 2,400 ft above sea level. Within three miles the land runs from 2,270 ft to 3,810 ft, a difference of 1,540 ft: steep hill country. The highest named summit within 15 miles is Snake Mountain, about 5,550 ft, 11 miles south-southeast.

Under the town center the state geologic map shows Shady Dolomite (dolostone, limestone), from the Cambrian, 487 to 542 million years old.

The section below crosses 9 rock units mapped at the surface.
