I'll bet most of you don't know that there's a large sandy area at Kincaid Park in Anchorage, near the headwaters of the Cook Inlet.
The last time I visited the dunes, there were dirt bikers racing and jumping on the sand. Here's an article from the Alaska Dispatch, talking about the area & how it relates to our glacial past.

So this "deposited sand" from the last ice age vs being sand made from ocean action?
That's correct; my understanding is that the area where it's deposited is at the point where the ice sloped down to what is now sea level, on its way to gouge out the bottom of the Inlet.
OK, then it's like the sand dunes in Wisconsin, Illinois, and Indiana.
When the glaciers scooped out the Great Lakes, they dumped a LOT of stuff all around the edges!
Exactly, drjim, just like the Homer Spit: a three-mile long tongue of sand & rock snaking out into the middle of Kachemak Bay. Debris, good and proper.
Except the sand in Illinois, Wisconsin and Michigan occasionally thaws. Are you sure those are sand grains and not ice crystals? :)
Preppy, we're pretty sure: the ice crystals would be a different shade of grey. :)
Gotta be one COLD beach....
Only in the winter, NFO. :^)
