This peak along the Glenallen Highway in the Matanuska Valley between Palmer and Matanuska Glacier. (I have some reason to believe it’s not Mt. McKinley.)
A quick fly up the valley in Google Earth and a peek at the USGS Topo map…
King’s Mountain. And a corroborating photograph!: http://www.andrewskurka.com/AK09/pictures/6.php (bottom of the page)
I suppose at 5,800 feet it’s a bit smaller than McKinley!
Aha! Thank you!
ETA: Well, well, well!
