The orange travertine (mineral deposits) built up between the geyser and the river are beautiful and fun to walk around. It looks somewhat like the inside of a cave only it's outside. We were there between 1:30-2:30 pm and the geyser was bubbling the whole time. No big eruptions though. The rock formations behind the geyser are pretty and were also fun to climb on. There was a big group with at least 14 ATVs when we got there which was also fun to see.
