Those wooden walkways must be a nice way to walk over the marshes. In Yellowstone they have some of those in the geyser fields so you don't accidentally fall through weak rock covering a boiling hot pool of water.
I love that last picture, just a nice view down the trail with the fall leaves on the ground. Too bad winter is there in full force right now!
I would love to go to Yellowstone. Definitely on my bucket list of places to go. Thanks for stopping in.
