AIR MAIL

Where today’s air came from

The air arriving over Heath about 5,000 feet above the ground was over British Columbia three days ago, and over Ontario a day ago, about 2,410 miles back along its path. It came down from about 9,600 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. 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 Heath stands on

Heath’s center stands about 1,610 ft above sea level. Within three miles the land runs from 1,260 ft to 2,010 ft, a difference of 750 ft: hilly country. The highest named summit within 15 miles is Edeburn Hill, about 1,950 ft, 2 miles southwest.

Under the town center the state geologic map shows Shenango Formation through Oswayo Formation, undivided (sandstone, siltstone, shale), from the Devonian to Carboniferous, 324 to 422 million years old.

The section below crosses 3 rock units mapped at the surface.
