AIR MAIL

Where today’s air came from

The air arriving over Lorimor about 5,000 feet above the ground was over the northern Rockies three days ago, and over the southern Plains a day ago, about 900 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Rockies. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THE GROUND

What Lorimor stands on

Lorimor’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,100 ft to 1,230 ft, a difference of 130 ft: gently rolling country.

Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Late Pennsylvanian, 299 to 307 million years old.
