You don’t necessarily notice the colors on the dunes until you’re up close – or after a particularly rainy spring. Reminds me a bit of the desert wildflowers, only with the fog and ocean instead of the heat and tumbleweeds. Color me grateful.

Beautiful photo! The wildlfowers are blooming so late this year – makes for such pleasurable dune walking.
I love this photo, too. You capture the “carpet” effect really well.
