AIR MAIL

Where today’s air came from

The air arriving over St. Regis about 5,000 feet above the ground was over the Pacific north of Hawaii three days ago, and over the Pacific Northwest a day ago, about 1,360 miles back along its path. It came down from about 14,700 feet up, warming and drying as it sank. Near the ground the air came from the Pacific Northwest; at 10,000 feet, from the Pacific north of Hawaii. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THE GROUND

What St. Regis stands on

St. Regis’s center stands about 2,660 ft above sea level. Within three miles the land runs from 2,600 ft to 4,750 ft, a difference of 2,150 ft: mountain country. The highest named summit within 15 miles is Lost Peak, about 7,370 ft, 13 miles south.

Under the town center the state geologic map shows Gravel, from the Pleistocene to Holocene, less than 1.8 million years old.

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

Rock at the surface along the line

Quartzite, argillite, metasiltstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 9 mi of the line.

Gravel

Age: Pleistocene to Holocene, less than 1.8 million years old. About 1 mi of the line.

Sediment or sedimentary rock

Sedimentary. Age: Tertiary, 2.6 to 66 million years old. About 0.9 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 St. Regis’s rain goes

A raindrop that lands in St. Regis reaches the Pacific Ocean by way of the Clark Fork, the Pend Oreille and the Columbia: about 980 river miles.

THE WAY DOWN, TO SCALE
St. Regis≈ 980 mi · the Pacific Ocean
FROM THE CENTER OF ST. REGIS ≈ 980 mi to the Pacific Ocean Clark Fork → Pend Oreille → Columbia

Lakes on the way: Lake Pend Oreille, Lake Umatilla and Noxon Rapids Reservoir.

460 miles of the trip are on the Columbia.

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