AIR MAIL

Where today’s air came from

The air arriving over Prospect about 5,000 feet above the ground was over the Gulf of Alaska three days ago, and over the northern Plains a day ago, about 3,240 miles back along its path. It came down from about 14,000 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Pacific north of Hawaii. 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.

THIS WEEK, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

77° on Nov. 11, 2020, the hottest reading for this week of the year since 1917. Next is 75° in 1949.

THE GROUND

What Prospect stands on

Prospect’s center stands about 910 ft above sea level. Within three miles the land runs from 900 ft to 980 ft, a difference of 80 ft: gently rolling country.

Under the town center the state geologic map shows Salina Group (dolostone), from the Silurian, 422 to 445 million years old.

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