AIR MAIL

Where today’s air came from

The air arriving over Carbon Hill about 5,000 feet above the ground was over British Columbia three days ago, and over the northern Plains a day ago, about 1,820 miles back along its path. It rose from near the ground on the way. 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.

3° on Nov. 17, 1959, the coldest reading for this week of the year since 1911. Next is 4° in 1933.

THE GROUND

What Carbon Hill stands on

Carbon Hill’s center stands about 570 ft above sea level. Within three miles the land runs from 530 ft to 590 ft, a difference of 60 ft: gently rolling country.

Under the town center the state geologic map shows Carbondale Formation (shale, sandstone, coal), from the Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old.

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