AIR MAIL

Where today’s air came from

The air arriving over Henderson about 5,000 feet above the ground was over Texas three days ago, and over the southern Plains a day ago, about 860 miles back along its path. 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 Henderson stands on

Henderson’s center stands about 1,050 ft above sea level. Within three miles the land runs from 1,020 ft to 1,200 ft, a difference of 180 ft: gently rolling country.

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

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