AIR MAIL

Where today’s air came from

The air arriving over Hopewell about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,640 miles back along its path. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the open Pacific. 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 Hopewell stands on

Hopewell’s center stands about 100 ft above sea level. Within three miles the land runs from 10 ft to 140 ft, a difference of 130 ft: gently rolling country.

Under the town center the state geologic map shows Cohansey Formation (sand), from the Middle Miocene, 12 to 14 million years old.

The section below crosses 2 rock units mapped at the surface.
