AIR MAIL

Where today’s air came from

The air arriving over Crystal Lake Park about 5,000 feet above the ground was over the open Pacific three days ago, about 2,740 miles back along its path. It came down from about 11,900 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Rockies. It feels dry all the same. 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 Crystal Lake Park stands on

Crystal Lake Park’s center stands about 600 ft above sea level. Within three miles the land runs from 490 ft to 680 ft, a difference of 190 ft: gently rolling country.

Under the town center the state geologic map shows Meramecian Series (limestone), from the Carboniferous, 324 to 359 million years old.

The section below crosses 5 rock units mapped at the surface.
