AIR MAIL

Where today’s air came from

The air arriving over May about 5,000 feet above the ground was over Texas three days ago, about 410 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. Near the ground the air came from Texas; at 10,000 feet, from the southern Rockies. 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 May stands on

May’s center stands about 2,040 ft above sea level. Within three miles the land runs from 2,020 ft to 2,200 ft, a difference of 180 ft: gently rolling country.

Under the town center the state geologic map shows Terrace Deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.

The section below crosses 6 rock units mapped at the surface.

Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Rock at the surface along the line

Terrace Deposits

Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 10 mi of the line.

Rush Springs Formation

Sandstone. Age: Permian, 252 to 299 million years old. About 6 mi of the line.

Ogallala Formation

Fine-detrital, coarse-detrital. Age: Pliocene, 2.6 to 5.3 million years old. About 6 mi of the line.

Marlow Formation

Sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 0.9 mi of the line.

Cloud Chief Formation

Shale, siltstone, sandstone. Age: Permian, 252 to 299 million years old. About 0.8 mi of the line.

Alluvium

Fine-detrital. Age: Holocene, less than 12,000 years old. About 0.5 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.

THE WATER

Where May’s rain goes

A raindrop that lands in May reaches the Gulf of America by way of the Beaver, the North Canadian, the Canadian, the Arkansas and the Mississippi: about 1,520 river miles.

THE WAY DOWN, TO SCALE
May≈ 1,520 mi · the Gulf of America
FROM THE CENTER OF MAY ≈ 1,520 mi to the Gulf of America Beaver → North Canadian → Canadian → Arkansas → Mississippi

Lakes on the way: Canton Lake, Murray Lake and Ozark 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 May; river miles along the main stem, rounded.
