Here is the view from Sleeping Bear Dunes National Lakeshore. We climbed a "small" dune, but did not opt for the 4 hour trek all the way up one and down the other in another part of the park.
I see from your other work that you use the Adamski Effect occasionally. I'm wondering what this scene, cropped as a vertical to include just the two figures in the middle, might look like using the Adamski Effect. I've never tried it. Your "What is Art" image has inspired me to explore it.
