AIR MAIL

Where today’s air came from

The air arriving over Santa Clara about 5,000 feet above the ground was over southern California three days ago, and over the California coast a day ago, about 540 miles back along its path. Most of the nine paths traced from around the city agree. It came down from about 11,800 feet up, warming and drying as it sank. Near the ground the air came from the California coast; at 10,000 feet, from southern California. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THE GROUND

What Santa Clara stands on

Santa Clara’s center stands about 80 ft above sea level. Within three miles the land runs from 20 ft to 160 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Mount Day, about 3,820 ft, 15 miles east-northeast.

Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
