Many thanks to Dave for bringing this to my attention. It shows the value of LIDAR imagery, and a huge amount of detail showing the relations between various types of glacial erosional and depositional landscapes. Puget Sound area? Now that looks like the sort of place I'd really like to visit.......

Close-up of part of the map, showing drumlins and fluted moraine --classic streamlining features. Not much doubt about the direction of ice flow here.........
What is fluted moraine not like flute casts?
