AIR MAIL

Where today’s air came from

The air arriving over First Mesa about 5,000 feet above the ground was over the central Plains three days ago, and over the southern Rockies a day ago, about 1,020 miles back along its path. It came down from about 13,100 feet up, warming and drying as it sank. 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 First Mesa stands on

First Mesa’s center stands about 5,770 ft above sea level. Within three miles the land runs from 5,590 ft to 6,200 ft, a difference of 610 ft: hilly country. The highest named summit within 15 miles is Antelope Mesa, about 6,620 ft, 11 miles east-southeast.

Under the town center the state geologic map shows Holocene surficial deposits (silt, clay), from the Holocene, less than 10,000 years old.

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

Rock at the surface along the line

Cretaceous sedimentary rocks

Sandstone, shale. Age: Late Cretaceous, 88 to 97 million years old. About 12 mi of the line.

Sedimentary rocks of the Late Cretaceous Mesaverde Group

Sandstone, shale, coal. Age: Late Cretaceous, 84 to 88 million years old. About 8 mi of the line.

Holocene surficial deposits

Silt, clay. Age: Holocene, less than 10,000 years old. About 3 mi of the line.

Pliocene to middle Miocene deposits

Conglomerate, sandstone. Age: Early Miocene to Pleistocene, 2 to 16 million years old. About 0.8 mi of the line.

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

THE WATER

Where First Mesa’s rain goes

A raindrop that lands in First Mesa reaches the Gulf of California by way of Polacca Wash, Corn Creek Wash, the Little Colorado and the Colorado: about 920 river miles.

THE WAY DOWN, TO SCALE
First Mesa≈ 920 mi · the Gulf of California
FROM THE CENTER OF FIRST MESA ≈ 920 mi to the Gulf of California Polacca Wash → Corn Creek Wash → Little Colorado → Colorado

Lakes on the way: Lake Mead, Lake Mohave and Lake Havasu.

290 miles of the trip are on the Colorado.

Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.

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