AIR MAIL

Where today’s air came from

The air arriving over New Effington about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the northern Plains a day ago, about 1,080 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. 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 New Effington stands on

New Effington’s center stands about 1,090 ft above sea level. Within three miles the land runs from 1,080 ft to 1,180 ft, a difference of 100 ft: gently rolling country.

Under the town center the state geologic map shows Carlile Shale, from the Late Cretaceous, 66 to 100 million years old.

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

Where New Effington’s rain goes

A raindrop that lands in New Effington reaches Hudson Bay by way of Cottonwood Slough, Jim Creek, the Bois de Sioux, the Red River of the North and the Nelson: about 1,260 river miles. Past the border it runs north through Canada to Hudson Bay.
