AIR MAIL

Where today’s air came from

The air arriving over Liberty about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,270 miles back along its path. It rose from near the ground on the way. 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 Liberty stands on

Liberty’s center stands about 610 ft above sea level. Within three miles the land runs from 470 ft to 1,340 ft, a difference of 870 ft: hilly country. The highest named summit within 15 miles is Catharines Crown, about 1,950 ft, 15 miles west-northwest.

Under the town center the state geologic map shows Hamilton Group (black-shale), from the Early Devonian to Middle Devonian, 384 to 422 million years old.

The section below crosses 8 rock units mapped at the surface.
