AIR MAIL

Where today’s air came from

The air arriving over Essex about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 2,410 miles back along its path. It came down from about 10,600 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from British Columbia. 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 Essex stands on

Essex’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 320 ft, a difference of 320 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Goose Hill, about 700 ft, 11 miles northwest.

Under the town center the state geologic map shows Rope Ferry Gneiss, from the Neoproterozoic, 617 to 623 million years old.

The section below crosses 8 rock units mapped at the surface.

Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
