AIR MAIL

Where today’s air came from

The air arriving over Hampton about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the central Plains a day ago, about 1,150 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the northern Plains. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

The hottest this week has been

76° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 76° in 2012.

THE GROUND

What Hampton stands on

Hampton’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,050 ft to 1,230 ft, a difference of 180 ft: gently rolling country.

Under the town center the state geologic map shows Kinderhookian formations (dolostone, limestone, siltstone), from the Early Mississippian, 347 to 359 million years old.

The section below crosses 4 rock units mapped at the surface.
