AIR MAIL

Where today’s air came from

The air arriving over Millstadt about 5,000 feet above the ground was over the open Pacific three days ago, about 2,990 miles back along its path. It came down from about 15,700 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Rockies. 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 Millstadt stands on

Millstadt’s center stands about 600 ft above sea level. Within three miles the land runs from 510 ft to 660 ft, a difference of 150 ft: gently rolling country.

Under the town center the state geologic map shows Shelburn-Patoka Formations undivided (shale, limestone), from the Late Pennsylvanian, 304 to 307 million years old.

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