AIR MAIL

Where today’s air came from

The air arriving over Brevort about 5,000 feet above the ground was over British Columbia three days ago, and over the Canadian Prairies a day ago, about 1,810 miles back along its path. It rose from near the ground on the way. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. It has stayed over land, which is why it feels dry. 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 Brevort stands on

Brevort’s center stands about 690 ft above sea level. Within three miles the land runs from 660 ft to 800 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Maple Hill, about 1,060 ft, 8 miles north-northeast.

Under the town center the state geologic map shows Engadine Dolomite (dolostone), from the Silurian, 428 to 445 million years old.

The section below crosses 6 rock units mapped at the surface.

THE WATER

Where Brevort’s rain goes

A raindrop that lands in Brevort reaches Lake Huron by way of Flat Creek and the Carp: about 9 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
