AIR MAIL

Where today’s air came from

The air arriving over Lukachukai about 5,000 feet above the ground was over the southern Rockies three days ago, and over Texas a day ago, about 780 miles back along its path. Most of the nine paths traced from around the city agree. 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 Lukachukai stands on

Lukachukai’s center stands about 6,560 ft above sea level. Within three miles the land runs from 6,230 ft to 7,640 ft, a difference of 1,410 ft: steep hill country. The highest named summit within 15 miles is Roof Butte, about 9,790 ft, 8 miles east-northeast.

Under the town center the state geologic map shows Early Pleistocene to latest Pliocene surficial deposits (gravel, sand), from the Late Pliocene to Pleistocene, 0.8 to 3 million years old.

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

Rock at the surface along the line

Gravel, sand. Age: Late Pliocene to Pleistocene, 0.8 to 3 million years old. About 4 mi of the line.

Middle Miocene to Oligocene volcanic rocks

Basalt, andesite, dacite. Age: Middle Eocene to Late Miocene, 11 to 38 million years old. About 1 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 Lukachukai’s rain goes

A raindrop that lands in Lukachukai reaches the Gulf of California by way of Tohotso Creek, Lukachukai Creek, Chinle Wash, Chinle Creek, the San Juan and the Colorado: about 1,100 river miles.

THE WAY DOWN, TO SCALE
Lukachukai≈ 1,100 mi · the Gulf of California
FROM THE CENTER OF LUKACHUKAI ≈ 1,100 mi to the Gulf of California Tohotso Creek → Lukachukai Creek → Chinle Wash → Chinle Creek → San Juan → Colorado

Lakes on the way: Lake Mead, Lake Powell, 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 Lukachukai; river miles along the main stem, rounded.
