AIR MAIL

Where today’s air came from

The air arriving over West Milton about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,280 miles back along its path. 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.

THIS WEEK, NINE YEARS AGO Nov. 11, 2017

The coldest this week has been

10° on Nov. 11, 2017, the coldest reading for this week of the year since 1996. Next is 15° in 2019.

THE GROUND

What West Milton stands on

West Milton’s center stands about 500 ft above sea level. Within three miles the land runs from 430 ft to 730 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Jones Mountain, about 2,180 ft, 14 miles west-southwest.

Under the town center the state geologic map shows Keyser and Tonoloway Formations, undivided (limestone), from the Silurian to Devonian, 359 to 445 million years old.

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