AIR MAIL

Where today’s air came from

The air arriving over Grampian about 5,000 feet above the ground was over Canada three days ago, and over the northern Plains a day ago, about 2,660 miles back along its path. It came down from about 13,500 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. It has stayed over land, which is why it feels dry. 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 Grampian stands on

Grampian’s center stands about 1,570 ft above sea level. Within three miles the land runs from 1,240 ft to 1,860 ft, a difference of 620 ft: hilly country. The highest named summit within 15 miles is Hobo Hill, about 2,280 ft, 11 miles north-northeast.

Under the town center the state geologic map shows Allegheny Formation (sandstone), from the Carboniferous, 299 to 324 million years old.

The section below crosses 5 rock units mapped at the surface.

Huntley Mountain Formation

Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.7 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 Grampian’s rain goes

A raindrop that lands in Grampian reaches Chesapeake Bay and the Atlantic Ocean by way of Kratzer Run, Anderson Creek, the West Branch Susquehanna and the Susquehanna: about 320 river miles.

THE WAY DOWN, TO SCALE
Grampian≈ 320 mi · Chesapeake Bay and the Atlantic Ocean
FROM THE CENTER OF GRAMPIAN ≈ 320 mi to Chesapeake Bay and the Atlantic Ocean Kratzer Run → Anderson Creek → West Branch Susquehanna → Susquehanna

Lake on the way: Lake Aldred.

180 miles of the trip are on the West Branch Susquehanna.

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