AIR MAIL

Where today’s air came from

The air arriving over Tremont about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,540 miles back along its path. It came down from about 9,600 feet up, warming and drying as it sank. Near the ground the air came from the northern Plains; at 10,000 feet, from the Gulf of Alaska. 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.

THE GROUND

What Tremont stands on

Tremont’s center stands about 790 ft above sea level. Within three miles the land runs from 720 ft to 1,630 ft, a difference of 910 ft: steep hill country. The highest named summit within 15 miles is Big Mountain, about 1,830 ft, 13 miles north.

Under the town center the state geologic map shows Llewellyn Formation (sandstone), from the Carboniferous, 299 to 324 million years old.

The section below crosses 13 rock units mapped at the surface.
