AIR MAIL

Where today’s air came from

The air arriving over Winchester about 5,000 feet above the ground was over Texas three days ago, and over the Ozarks a day ago, about 940 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from the southern Plains; 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 Winchester stands on

Winchester’s center stands about 850 ft above sea level. Within three miles the land runs from 680 ft to 1,000 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Dude Ranch Hill, about 1,050 ft, 3 miles southeast.

Under the town center the state geologic map shows Wewoka Formation (shale, sandstone), from the Carboniferous, 299 to 324 million years old.

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