AIR MAIL

Where today’s air came from

The air arriving over Spencer about 5,000 feet above the ground was over the Pacific off the Northwest three days ago, and over the Pacific Northwest a day ago, about 1,080 miles back along its path. It came down from about 13,200 feet up, warming and drying as it sank. Near the ground the air came from the Pacific Northwest; at 10,000 feet, from the Pacific off California. 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 IN 1955 Nov. 16, 1955

−15° on Nov. 16, 1955, the coldest reading for this week of the year since 1925. Next is −8° in 1959.

What Spencer stands on

Spencer’s center stands about 5,910 ft above sea level. Within three miles the land runs from 5,740 ft to 7,120 ft, a difference of 1,380 ft: steep hill country. The highest named summit within 15 miles is Lookout Point, about 8,680 ft, 9 miles northeast.

Under the town center the state geologic map shows Sedimentary rocks (Paleocene and Cretaceous) (conglomerate, sandstone), from the Cretaceous to Paleocene, 56 to 145 million years old.

The section below crosses 7 rock units mapped at the surface.
