AIR MAIL

Where today’s air came from

The air arriving over Seaton about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the central Plains a day ago, about 1,270 miles back along its path. Most of the nine paths traced from around the city agree. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK IN 2015 Nov. 17–18, 2015

The wettest two days this week has seen

3.42 inches of rain fell in two days, the most for this week of the year since records began in 1900. The next wettest, 2.98 inches, fell in 1928.

THE GROUND

What Seaton stands on

Seaton’s center stands about 610 ft above sea level. Within three miles the land runs from 570 ft to 670 ft, a difference of 100 ft: gently rolling country.

Under the town center the state geologic map shows Muscatatuck Group (limestone), from the Middle Devonian, 384 to 394 million years old.

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