AIR MAIL

Where today’s air came from

The air arriving over Port Colden about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,660 miles back along its path. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. 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.

What Port Colden stands on

Port Colden’s center stands about 530 ft above sea level. Within three miles the land runs from 380 ft to 980 ft, a difference of 600 ft: hilly country. The highest named summit within 15 miles is Scotts Mountain, about 1,290 ft, 6 miles west.

Under the town center the state geologic map shows Microperthite Alaskite (granite), from the Mesoproterozoic, 1 to 1.6 billion years old.
