AIR MAIL

Where today’s air came from

The air arriving over Aspinwall about 5,000 feet above the ground was over Canada three days ago, and over the northern Plains a day ago, about 2,730 miles back along its path. It came down from about 15,300 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the open Pacific. 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.

THIS WEEK, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

74° on Nov. 11, 2020, the hottest reading for this week of the year since 1905. Next is 70° in 2021.

THE GROUND

What Aspinwall stands on

Aspinwall’s center stands about 770 ft above sea level. Within three miles the land runs from 710 ft to 1,250 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Rich Hill, about 1,290 ft, 7 miles north-northeast.

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 3 rock units mapped at the surface.
