The best book about Yellowstone's geysers is The Geysers of Yellowstone by T. Scott Bryan. According to a couple of geyser gazers we met in October, a new edition of the book should be coming out soon.
Here are most of the geysers we've seen erupting with links to videos of each:
White Dome- This is our favorite geyser. It is small, but erupts from a huge sinter cone. The orifice (hole where the water sprays from) is only 4 inches wide and will probably soon close completely off. We love it because it erupts from high up and the spray of water is narrow. Irregular interval, but usually fairly short. Duration 2 minutes and 10-30 feet high.
Great Fountain- This is a beautiful geyser. It erupts from a terraced sinter cone. The eruption begins about an hour after the crater fills and begins to overflow. A prediction is often posted on the sign near the geyser, and you can see this geyser from the road. 8-12 hour interval and a one hour duration. 75-250 feet, but usually around 100 feet.
Clepsydra- Lower Geyser Basin, erupts almost continuously. If you come in from the West or North (and possibly East) Entrances, this is probably the first geyser you'll see erupting.
Daisy- Daisy is actually the most reliable geyser in the Upper Geyser Basin (including Old Faithful). However, wind and thunderstorms can delay eruptions. Usually it's easy to see. About a 2 hour interval with a 3-4 minute duration. The prediction for Daisy is posted in the Old Faithful Visitor Center.
Grand- This really is a grand geyser to see. It gets very high, and you can see it over the trees. Since the duration is about 10 minutes, you often have time to run over when you see it start to erupt. Interval about 8 hours; the prediction is posted in the Old Faithful Visitor Center.
Spasmodic and Sawmill- These two geysers are close together in the Upper Geyser Basin. They are rather noisy geysers, and could have subterranean connections. Both are only a few feet high.
Beehive- We've been lucky enough to see this one twice. It is sometimes predictable; we just happened to be in the right place at the right time. It erupts for several minutes and you don't have to be right next to it to see it. It also is near Old Faithful, so often people see Beehive erupt while they're waiting for Old Faithful. Interval often around 15 hours.
Cliff- This geyser is right next to a creek, but you can't tell from the video. Fun to watch. Black Sand Basin, irregular interval and duration.
