AIR MAIL

Where today’s air came from

The air arriving over Buffalo about 5,000 feet above the ground was over the Pacific off the Northwest three days ago, and over the northern Rockies a day ago, about 1,000 miles back along its path. It came down from about 14,500 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 off California. 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 Buffalo stands on

Buffalo’s center stands about 4,640 ft above sea level. Within three miles the land runs from 4,490 ft to 5,180 ft, a difference of 690 ft: hilly country. The highest named summit within 15 miles is Hunter Mesa, about 8,080 ft, 13 miles west.

Under the town center the state geologic map shows Wasatch Formation (mudstone, sandstone), from the Eocene, 34 to 56 million years old.

The section below crosses 9 rock units mapped at the surface.

THE WATER

Where Buffalo’s rain goes

A raindrop that lands in Buffalo reaches the Gulf of America by way of French Creek, Clear Creek, the Powder River, the Yellowstone, the Missouri and the Mississippi: about 3,220 river miles.

THE WAY DOWN, TO SCALE
Buffalo≈ 3,220 mi · the Gulf of America
FROM THE CENTER OF BUFFALO ≈ 3,220 mi to the Gulf of America French Creek → Clear Creek → Powder River → Yellowstone → Missouri → Mississippi

Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Sharpe and Lake Francis Case.

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 Buffalo; river miles along the main stem, rounded.
