I've been waiting a long time for the right people to start some geyser blogs. And finally there are a few. The first is an Amazon blog by Janet Chapple, the author of Yellowstone Treasures. This is more of a general blog about Yellowstone with lots of geysers mixed in.
But the real geyser blog is now at Geyser Notes. It's written by a geyser veteran and is thoroughly enjoyable to read. Yesterday's post about cleaning vents isn't something you can read just anywhere. You can also find more geyser info on the main page at Geyser Information. Thanks Heinrich!
