AIR MAIL

Where today’s air came from

The air arriving over Evansville about 5,000 feet above the ground was over the Pacific Northwest three days ago, and over the northern Rockies a day ago, about 690 miles back along its path. Most of the nine paths traced from around the city agree. It came down from about 14,500 feet up, warming and drying as it sank. Near the ground the air came from the Pacific off the Northwest; at 10,000 feet, from the Great Basin. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THE GROUND

What Evansville stands on

Evansville’s center stands about 5,120 ft above sea level. Within three miles the land runs from 5,080 ft to 5,440 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Muddy Mountain, about 8,290 ft, 12 miles south.

Under the town center the state geologic map shows Alluvium and Colluvium (clay, silt, sand), from the Pleistocene to Holocene, less than 2.6 million years old.

The section below crosses 12 rock units mapped at the surface.
