AIR MAIL

Where today’s air came from

The air arriving over Augusta about 5,000 feet above the ground was over the open Pacific three days ago, and over the central Plains a day ago, about 2,790 miles back along its path. It came down from about 16,400 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.

What Augusta stands on

Augusta’s center stands about 660 ft above sea level. Within three miles the land runs from 530 ft to 740 ft, a difference of 210 ft: rolling country.

Under the town center the state geologic map shows Augusta Group (dolostone, limestone), from the Early Mississippian to Middle Mississippian, 331 to 359 million years old.
