Grand Canyon in Yellowstone

There are two main loops to do in Yellowstone, today we did the south loop covering a lot of the thermal areas and also this astonishing Canyon. We woke up to quite a heavy frost which was a bit of a surprise and caused it to be very foggy in the thermal area - we will visit them again tomorrow for better sights, hopefully. The afternoon was a balmy 70° and we headed over to the Lamar Valley to gave a look for more wild life.
