AIR MAIL

Where today’s air came from

The air arriving over Quemahoning about 5,000 feet above the ground was over Canada three days ago, and over Ontario a day ago, about 2,720 miles back along its path. It came down from about 15,400 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the Pacific north of Hawaii. 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.

THE GROUND

What Quemahoning stands on

Quemahoning’s center stands about 2,050 ft above sea level. Within three miles the land runs from 1,650 ft to 2,280 ft, a difference of 630 ft: hilly country. The highest named summit within 15 miles is Bald Knob, about 2,960 ft, 13 miles west.

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

The section below crosses 6 rock units mapped at the surface.
