AIR MAIL

Where today’s air came from

The air arriving over California Junction about 5,000 feet above the ground was over Texas three days ago, about 840 miles back along its path. It rose from near the ground on the way. Near the ground the air came from the northern Plains; at 10,000 feet, from the southern Rockies. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THE GROUND

What California Junction stands on

California Junction’s center stands about 1,000 ft above sea level. Within three miles the land runs from 980 ft to 1,040 ft, a difference of 60 ft: nearly flat ground.

Under the town center the state geologic map shows Lower Cherokee Group and Raccoon Creek Group (shale, sandstone, siltstone), from the Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old.

The section below crosses 7 rock units mapped at the surface.
