We toured the upper geyser basin yesterday and were amazed at how many other fairly predictable cone geysers there are in addition to Old Faithful!  One of the most impressive is the Grand Geyser, which is predictable to +-90 minutes so it’s one that people will sit and wait for an eruption.  We did, and we only had to wait about 15 minutes to see it erupt!

Two other really unusual geysers are the Grotto geyser, named that because it has holes in the cone that make it look like a grotto, and the Castle geyser, from most angles it does look like a castle!

I added some photos of pools and other geysers we saw.  AND, at one point while walking along the boardwalk (people have to stay on paths or boardwalks because of the fragile state of the geysers, pools, earth crust – people used to break through the crust and get burned!) we saw fairly fresh grizzly tracks right next to the boardwalk!  In a pretty popular area of the park that is visited by thousands of people each day!

Here are the photos we took:
