Now that I’ve completed a bunch of books, its time to start sharing mudpot and geyser photos. This high speed mudpot burst shows hidden object patterns like those in Look! What’s that Lurking in the Mudpots?. Details are at www.mudpot.com . Do you see the hidden face in the image? The pictures span 40 years and locations around the world. I’m addicted to mud patterns of all sorts; splasher mudpots, mud bursts, mud volcanoes, mud geysers, explosion craters and swirling patterns in quiet pools. I hope to post more pictures to support discussions about mudpots.

I became fascinated with geysers that form blue bubbles at the start of their eruptions. These consist of a doming up of the water before turning to a normal geyser eruption. Botryoidal Spring became a geyser in 1996 when I first noticed its amazing bubble shapes. Using the same camera techniques as for mudpots, similar surface patterns were revealed. Here’s a more recent example taken a half second into the eruption. My new book, Unusual Geysers, is about these geysers. An animation of a similar eruption is shown at www.mudpot.com. Spanning two seconds, its water rises, creates a bubble. then turns to spray.
