AIR MAIL

Where today’s air came from

The air arriving over Bath about 5,000 feet above the ground was over the open Pacific three days ago, and over the central Plains a day ago, about 2,770 miles back along its path. It came down from about 15,000 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from British Columbia. 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 Bath stands on

Bath’s center stands about 470 ft above sea level. Within three miles the land runs from 430 ft to 520 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Kingfisher Hill, about 620 ft, 12 miles southeast.

Under the town center the state geologic map shows St. Louis Limestone, from the Middle Mississippian, 331 to 347 million years old.

The section below crosses 4 rock units mapped at the surface.

Rock at the surface along the line

Warsaw Formation and Salem Limestone

Limestone. Age: Middle Mississippian, 331 to 347 million years old. About 3 mi of the line.
