AIR MAIL

Where today’s air came from

The air arriving over South Bristol about 5,000 feet above the ground was over the Canadian Prairies three days ago, and over the Great Lakes a day ago, about 2,090 miles back along its path. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from Canada. 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.

THIS WEEK, FOUR YEARS AGO Nov. 12, 2022

The hottest this week has been

72° on Nov. 12, 2022, the hottest reading for this week of the year since 1996. Next is 67° in 2020.

THE GROUND

What South Bristol stands on

South Bristol’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 200 ft, a difference of 200 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Mount Hunger, about 310 ft, 8 miles north-northwest.

Under the town center the state geologic map shows Ordovician - Precambrian Z Cape Elizabeth Formation (slate), from the Neoproterozoic to Ordovician, 445 to 1,000 million years old.

The section below crosses 3 rock units mapped at the surface.
