LAKE CRESCENT — There just may be a bump on a log in a hole in the bottom of the sea.
But there’s a mountain smack in the middle of Lake Crescent, for certain — and a trench nearby that may hold an unbroken geological record of the region since the last Ice Age.
Veteran diver Bill Walker of Burien said Sunday he discovered the 450-foot-high mount on Aug. 11 and returned to it with other divers Saturday.
“It comes up dramatically, right center in the middle of the lake,” he said, and covers about two-thirds of an acre.
Maps of the lake say it is supposed to be 500 feet deep at that spot — latitude north 48 degrees, 4 minutes, 29 seconds, and longitude west 123 degrees, 47 minutes, 91 seconds, according to Walker’s global positioning system.
It lies six-tenths of a mile due magnetic north of the Barnes Point boat launch, he said.
The mount — which geologists would call a moraine — looks as if a giant barge filled with mammoth rocks tipped its load into the lake, Walker said.
