Mud pots can change, new ones appear. But as for mud pots around Imperial, this is not new. I can do no better than quote from Allen & Day: "The Imperial Group includes Imperial and Spray Geysers and a considerable number of small mud-pots and mud-springs surrounding the former..."

I've never seen anything about mud pots at or near Imperial in any of the sources I've consulted (certainly not an exhaustive list) and have been wondering whether this is a new feature. Anybody got anything on it? I can post a not-very-impressive photograph if there's interest. -------------- next part -------------- An HTML attachment was scrubbed...
