AIR MAIL

Where today’s air came from

The air arriving over Sunshine about 5,000 feet above the ground has hardly traveled: three days ago it was within 40 miles of here, drifting in light winds. It came down from about 11,100 feet up, warming and drying as it sank. 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 Sunshine stands on

Sunshine’s center stands about 7,360 ft above sea level. Within three miles the land runs from 6,150 ft to 8,680 ft, a difference of 2,530 ft: mountain country. The highest named summit within 15 miles is Apache Peak, about 13,400 ft, 15 miles west.

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 11 rock units mapped at the surface.

THE WATER

Where Sunshine’s rain goes

A raindrop that lands in Sunshine reaches the Gulf of America by way of Boulder Creek, Saint Vrain Creek, the South Platte, the Platte, the Missouri and the Mississippi: about 2,390 river miles.
