There is even a "Quake Lake" there which didn't exist before the quake. The shift in topography led to the formation of a new lake. Also I read that most of the geysers in Yellowstone erupted simultaneously, induced by the quake.

I'm not aware of that geyser event, although I do believe there was some disruption of usual cycles. There were some roads closed in Yellowstone due to the quake and alternative, previously closed, roads were used for evacuation of park visitors. The Earthquake Visitor Center is worth a stop. The events of the quake are hard to appreciate without some guidance from the visitor center so best to visit that prior to driving East to Yellowstone. Some of the more interesting relics of the quake are the massive landslide that created quake lake, the "ghost cabins" which floated off foundations and were deposited far from the current water line, remains of houses that slipped into Hebgen Lake, and faultlines visible along the hills nearby. There were something like 29 deaths and it was the peak of tourist season in the area so there were many people impacted. Lots of tragic and near humorous stories. The most remarkable aspect of the quake, my opinion, was a hurricane force wind that carried away more than a few campers. The wind was created by the sudden collapse of a huge section of mountain that slid into the Madison River Drainage.

Quake Lake and the slide that dammed the Madison River:

Sweet.
I don't remember seeing that photo before. It would have been taken sometime after the river channel was opened. The river initially (for several weeks, I believe) was completely blocked and there was an evacuation of the downstream town (Ennis) in the event of sudden collapse of the obstruction while the Corp of Engineers worked frantically to open a channel in a controlled fashion.

The aerial photo gives a better idea of the extent of the landslide than one gets by driving on the (now reconstructed) road along the river.
