Delta upon Delta
For some reason the last few days have seen me browsing the semi-frozen areas of the Earth and in my search for the perfect thermokarst landscape, I’ve run across some really nice deltas. I don’t know anything about the one below other than its location in far northwestern Saskatchewan, but it looks to me like this river had built a beautiful fan delta only to see the lake shoreline dramatically change (perhaps as a result of isostatic rebound?) triggering the building of not one, but two, new fan deltas like Mickey Mouse ears on the margins of the old one.
