AIR MAIL

Where today’s air came from

The air arriving over Robbinsville about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,820 miles back along its path. It came down from about 10,100 feet up, warming and drying as it sank. 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 Robbinsville stands on

Robbinsville’s center stands about 140 ft above sea level. Within three miles the land runs from 60 ft to 180 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Mount Canoe, about 500 ft, 15 miles west-northwest.

Under the town center the state geologic map shows Merchantville Formation (sand), from the Late Cretaceous, 72 to 84 million years old.
