AIR MAIL

Where today’s air came from

The air arriving over Hanover about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the northern Plains a day ago, about 1,320 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 Hanover stands on

Hanover’s center stands about 650 ft above sea level. Within three miles the land runs from 600 ft to 960 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Scales Mound, about 1,180 ft, 15 miles north.

Under the town center the state geologic map shows Galena Group (Trenton Limestone) (dolostone, limestone), from the Late Ordovician, 447 to 459 million years old.

The section below crosses 7 rock units mapped at the surface.
