This beach is west of Anchorage, near where Cook Inlet splits to form Turnagain Arm and Knik Arm (this beach is on the latter). The tide range is large, the silt load is huge, and the beach was sort of weird. High sandy-gravel bluffs. Sand ripples on a gravel beach with a thin coating of silt on the sand. The ripples appeared to be around mid-tide and I suspect they reflect the role of fast tidal currents along the shore of the point. The silt seems inevitable given the muddy water.
This beach is particularly impressive when a 747 takes off to the north.
