AIR MAIL

Where today’s air came from

The air arriving over Marine about 5,000 feet above the ground was over the open Pacific three days ago, and over Ontario a day ago, about 2,910 miles back along its path. It came down from about 13,800 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 Marine stands on

Marine’s center stands about 530 ft above sea level. Within three miles the land runs from 470 ft to 550 ft, a difference of 80 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 2 rock units mapped at the surface.
