AIR MAIL

Where today’s air came from

The air arriving over Lazy Acres about 5,000 feet above the ground was over the southern Rockies three days ago, about 480 miles back along its path. Most of the nine paths traced from around the city agree. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THIS WEEK, TEN YEARS AGO Nov. 17, 2016

The hottest this week has been

70° on Nov. 17, 2016, the hottest reading for this week of the year since 1978. Next is 67° in 2005.

THE GROUND

What Lazy Acres stands on

Lazy Acres’s center stands about 7,020 ft above sea level. Within three miles the land runs from 5,490 ft to 8,250 ft, a difference of 2,760 ft: mountain country. The highest named summit within 15 miles is Saint Vrain Mountain, about 12,150 ft, 14 miles west-northwest.

Under the town center the state geologic map shows Granitic rocks of 1700-m.y. age group (granite), from the Paleoproterozoic, 1.6 to 2.5 billion years old.

The section below crosses 15 rock units mapped at the surface.
