AIR MAIL

Where today’s air came from

The air arriving over Long Creek about 5,000 feet above the ground was over the California coast three days ago, and over the Pacific Northwest a day ago, about 840 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from the Pacific off the Northwest; at 10,000 feet, from the open Pacific. 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.

THE GROUND

What Long Creek stands on

Long Creek’s center stands about 3,740 ft above sea level. Within three miles the land runs from 3,530 ft to 5,330 ft, a difference of 1,800 ft: steep hill country. The highest named summit within 15 miles is Black Butte, about 6,220 ft, 12 miles south.

Under the town center the state geologic map shows Picture Gorge Basalt, from the Early Miocene to Middle Miocene, 12 to 23 million years old.
