AIR MAIL

Where today’s air came from

The air arriving over Marysville about 5,000 feet above the ground was over the southern Plains three days ago, about 720 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. 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 central Plains. 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.

THE GROUND

What Marysville stands on

Marysville’s center stands about 740 ft above sea level. Within three miles the land runs from 710 ft to 910 ft, a difference of 200 ft: rolling country.

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 3 rock units mapped at the surface.

Rock at the surface along the line

Lower Cherokee Group and Raccoon Creek Group

Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 20 mi of the line.

St. Louis and Pella Formations

Dolostone, limestone. Age: Middle Mississippian to Late Mississippian, 324 to 347 million years old. About 2 mi of the line.

Upper Cherokee Group

Shale, siltstone. Age: Middle Pennsylvanian, 307 to 315 million years old. About 2 mi of the line.
