Lake Superior, the superior lake.
I’ll be gone on a backpacking trip in the Porcupine Mountains for the next few days. I’ll be out of internet/Tumblr reach, but I’m sure things will continue as normal in my absence.
(Geological note: This is Jacobsville sandstone, from the eastern side of the Keweenaw peninsula (opposite the Porcupine Mountain area). But still, it’s a nice photo, no?)
