AIR MAIL

Where today’s air came from

The air arriving over Cook about 5,000 feet above the ground was over Canada three days ago, and over Ontario a day ago, about 2,690 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.

THIS WEEK IN 2002 Nov. 11, 2002

The hottest this week has been

75° on Nov. 11, 2002, the hottest reading for this week of the year since 1943. Next is 75° in 2020.

THE GROUND

What Cook stands on

Cook’s center stands about 1,390 ft above sea level. Within three miles the land runs from 1,280 ft to 2,150 ft, a difference of 870 ft: hilly country. The highest named summit within 15 miles is Bald Knob, about 2,960 ft, 6 miles southeast.

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 7 rock units mapped at the surface.
