A thermal explosion and eruption occurred a couple of days ago and rearranged the topography of the three most visited pools along the boardwalk.
.. The debris field, scoured outwash area, and boiling muck now clouding Opal Pool give testimony to the forces at work just below the feet of wading fisher folk: or for that matter, any folk in Yellowstone.
.. Eyewitness reports place the vertical displacement of water at about 70 feet. It was a large single column of water the erupted with a violent explosion and showered debris into the three previously separate pools along the boardwalk.

.. Only a few faithful geyser gazers were present for the eruption. Hoards of visitors are
.. We're going to make up for not fishin' by going fishing. Golly gee, there's only seven days left.
