Grotto
The Grotto Geyser is in the Upper Geyser Basin. It is located between Riverside and Grand Geysers. This is one I had never seen before, so I was thrilled I got to see it.
I wanted call it the "Washing Machine" because it has all these chambers that water surges through. If you should get there, try to see it. It erupts for around 2 hours. Jet geyser is a predictor for Grotto.
