AIR MAIL

Where today’s air came from

The air arriving over Mariaville Lake about 5,000 feet above the ground was over Canada three days ago, and over the Great Lakes a day ago, about 2,520 miles back along its path. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from British Columbia. 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 Mariaville Lake stands on

Mariaville Lake’s center stands about 1,300 ft above sea level. Within three miles the land runs from 780 ft to 1,440 ft, a difference of 660 ft: hilly country. The highest named summit within 15 miles is Rundy Cup Mountain, about 1,880 ft, 14 miles south-southwest.

Under the town center the state geologic map shows Schenectady Formation (graywacke, sandstone, siltstone), from the Late Ordovician, 445 to 459 million years old.

The section below crosses 7 rock units mapped at the surface.
