on the road

We spent alot of time at Mammoth Hot Springs on our first day in Yellowstone, I think we both agree that it was the most interesting geothermal area in the park. The formations you see are Travertine terraces, made from deposits of calcium carbonate in thermal water that bubbles to the surface. For more pictures of these two parks and more go to http://www.facebook.com/album.php?aid=194717&id=612725769&ref=mf , where you can find photos of our entire trip.
