I guess pilots can't also be considered geologists.

Alluvial fan - Wikipedia, the free encyclopedia

Looks to me like an alluvial fan formed from glacier run-off then subjected to rain on top of it creating the depression and smaller lake on top of it.

Shamrock Glacier, Jungle, in the first picture referencing the ring? Alaskan Atlas and Gazeteer page 80, D2?
Thanks for the heads up lat/lon wise Jungle. Never been there. Beautiful pictures you and FlyorDie have taken of the area.

It is fed/created by two glaciers that merge at this point.

Shamrock lake search brings up something on the Kenai, not this place, although FOD has the edge on local geography-it is not the geography of common usage, since there are no people nearby to utter such words.

Shamrock Lake it is: http://maps.google.com/maps?f=q&sour...86209&t=h&z=11

You may have to pan left to see it, N61225W152677 or thereabouts.
