AIR MAIL

Where today’s air came from

The air arriving over Ozone about 5,000 feet above the ground was over the central Plains three days ago, and over the Ozarks a day ago, about 820 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 southern Plains; 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.

THE GROUND

What Ozone stands on

Ozone’s center stands about 1,910 ft above sea level. Within three miles the land runs from 1,020 ft to 2,000 ft, a difference of 980 ft: steep hill country. The highest named summit within 15 miles is Garlands Knob, about 2,380 ft, 7 miles north-northwest.

Under the town center the state geologic map shows Atoka Formation, undivided (sandstone, black-shale), from the Carboniferous, 299 to 324 million years old.

The section below crosses 5 rock units mapped at the surface.

THE WATER

Where Ozone’s rain goes

A raindrop that lands in Ozone reaches the Gulf of America by way of Spadra Creek, the Arkansas and the Mississippi: about 870 river miles.

THE WAY DOWN, TO SCALE
Ozone≈ 870 mi · the Gulf of America
FROM THE CENTER OF OZONE ≈ 870 mi to the Gulf of America Spadra Creek → Arkansas → Mississippi

Lake on the way: Murray Lake.

600 miles of the trip are on the Mississippi.

Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ozone; river miles along the main stem, rounded.
