AIR MAIL

Where today’s air came from

The air arriving over Bolivar about 5,000 feet above the ground was over Canada three days ago, and over the Great Lakes a day ago, about 2,410 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. 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, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

74° on Nov. 11, 2020, the hottest reading for this week of the year since 1956. Next is 69° in 2012.

THE GROUND

What Bolivar stands on

Bolivar’s center stands about 1,610 ft above sea level. Within three miles the land runs from 1,550 ft to 2,390 ft, a difference of 840 ft: hilly country. The highest named summit within 15 miles is Alma Hill, about 2,570 ft, 8 miles east.

Under the town center the state geologic map shows Conneaut Group, undivided (shale, sandstone), from the Late Devonian, 359 to 384 million years old.
