AIR MAIL

Where today’s air came from

The air arriving over Homer about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,440 miles back along its path. 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.

THIS WEEK, SIX YEARS AGO Nov. 11, 2020

The hottest this week has been

75° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 68° in 2012.

THE GROUND

What Homer stands on

Homer’s center stands about 2,080 ft above sea level. Within three miles the land runs from 1,570 ft to 2,380 ft, a difference of 810 ft: hilly country. The highest named summit within 15 miles is Sweden Hill, about 2,580 ft, 10 miles northeast.

Under the town center the state geologic map shows Catskill Formation (sandstone, siltstone, shale), from the Late Devonian, 359 to 384 million years old.

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