AIR MAIL

Where today’s air came from

The air arriving over Lake Crystal about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the central Plains a day ago, about 840 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It rose from near the ground on the way. Near the ground the air came from British Columbia; at 10,000 feet, from the Pacific north of Hawaii. 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 Lake Crystal stands on

Lake Crystal’s center stands about 1,000 ft above sea level. Within three miles the land runs from 960 ft to 1,010 ft, a difference of 50 ft: nearly flat ground.

Under the town center the state geologic map shows Upper Cambrian (sandstone, siltstone, shale), from the Cambrian, 487 to 497 million years old.
