AIR MAIL

Where today’s air came from

The air arriving over Mahanoy about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,350 miles back along its path. It rose from near the ground on the way. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. It feels dry all the same. 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 Mahanoy stands on

Mahanoy’s center stands about 1,500 ft above sea level. Within three miles the land runs from 1,170 ft to 1,940 ft, a difference of 770 ft: hilly country. The highest named summit within 15 miles is Bears Head, about 2,090 ft, 4 miles east-northeast.

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

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

Rock at the surface along the line

Pottsville Formation

Sandstone. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.

Llewellyn Formation

Sandstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.

Mauch Chunk Formation

Shale, siltstone, sandstone. Age: Carboniferous, 324 to 359 million years old. About 6 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
