AIR MAIL

Where today’s air came from

The air arriving over Y-O Ranch about 5,000 feet above the ground was over the Pacific Northwest three days ago, and over the northern Rockies a day ago, about 910 miles back along its path. It came down from about 13,900 feet up, warming and drying as it sank. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THE GROUND

What Y-O Ranch stands on

Y-O Ranch’s center stands about 4,870 ft above sea level. Within three miles the land runs from 4,580 ft to 4,930 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Eagles Nest, about 5,100 ft, 10 miles east.

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 15×. 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

Dune sand and loess

Sand, unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 14 mi of the line.

Lower Miocene and Upper Oligocene rocks or rocks equivalent to Upper and Lower Miocene rocks and White River Formation

Sandstone, siltstone, claystone. Age: Late Oligocene to Late Miocene, 5.3 to 28 million years old. About 5 mi of the line.

White River Formation - Upper conglomerate member

Conglomerate, conglomerate-sandstone. Age: Oligocene, 23 to 34 million years old. About 3 mi of the line.

Gravel, pediment, and fan deposits

Gravel. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.7 mi of the line.

Alluvium and Colluvium

Clay, silt, sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.7 mi of the line.

White River Formation

Claystone, conglomerate. Age: Late Eocene to Early Oligocene, 31 to 35 million 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.

THE WATER

Where Y-O Ranch’s rain goes

A raindrop that lands in Y-O Ranch reaches the Gulf of America by way of Chugwater Creek, the Laramie, the North Platte, the Platte, the Missouri and the Mississippi: about 2,360 river miles.

THE WAY DOWN, TO SCALE
Y-O Ranch≈ 2,360 mi · the Gulf of America
FROM THE CENTER OF Y-O RANCH ≈ 2,360 mi to the Gulf of America Chugwater Creek → Laramie → North Platte → Platte → Missouri → Mississippi

Lake on the way: Grayrocks Reservoir.

1,170 miles of the trip are on the Mississippi.

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