Grant, that created Yellowstone as the world's first national park.   Karen Low  </blockquote> Hard to be sure, but from your description, this sounds like it may be the same thing that I saw on a trip during the summer of 2005.  It was pointed out to me by a summer intern of some denomination who was going to feed the report back through the chain, so it may already bear the name "Intern Geyser," which was suggested at the time.  Unfortunately, I didn't get a photo on that occasion (didn't realize until too late that it wasn't a "known" geyser), so have nothing to compare to. -- Bill Johnson</body> </html>
