AIR MAIL

Where today’s air came from

The air arriving over The College of New Jersey about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 2,270 miles back along its path. Near the ground the air came from the central Plains; 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 The College of New Jersey stands on

The College of New Jersey’s center stands about 130 ft above sea level. Within three miles the land runs from 20 ft to 240 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Sourland Mountain, about 640 ft, 14 miles north-northeast.

Under the town center the state geologic map shows Stockton Formation (arkose), from the Late Triassic, 202 to 237 million years old.
