Great first day of our USA trip. We left Bozeman and travelled along Paradise Valley pausing to see moraines and the Hepburn Mesa mammal fossil cliff before entering #yellowstonenationalpark Our first stop was #mammothhotsprings where we saw travertine terraces. We then stopped to examine tuff from the first Yellowstone caldera eruption (the largest known eruption on earth that emitted 2,500 km3 of lava) before reaching Sheepeater cliff to see #columnarbasalt We the passed #obsidiancliff en-route to the #norrisgeyserbasin where we saw the world's tallest #geyser Steamboat and #porcelainbasin We then checked out the Grand Canyon of Yellowstone from both the north and south rim, not only admiring the canyon and waterfalls but also seeing a cross section through a hydrothermal basin. We ended by seeing #tuffcliff which consists of #pyroclastic ash from the most recent Yellowstone Caldera eruption and the nearby Terrace Spring which bizarrely deposits both sinter and travertine. The night was spent in West Yellowstone. (at Yellowstone National Park) https://www.instagram.com/p/BpDsSMPA5fi/?utm_source=ig_tumblr_share&igshid=9trlbao8884c
