AIR MAIL

Where today’s air came from

The air arriving over Princeton about 5,000 feet above the ground was over the northern Plains three days ago, and over the southern Plains a day ago, about 860 miles back along its path. Most of the nine paths traced from around the city agree. It rose from near the ground on the way. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Rockies. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

What Princeton stands on

Princeton’s center stands about 950 ft above sea level. Within three miles the land runs from 820 ft to 1,040 ft, a difference of 220 ft: rolling country.

Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Carboniferous, 299 to 324 million years old.

The section below crosses 4 rock units mapped at the surface.
