We rested on a day trip to Yellowstone National Park where we joined the crowds to watch Old Faithful erupt on schedule, then took a walk to see some lesser-known but still spectacular bursts of hot, steamy water.
Riverside Geyser erupted for 20 minutes, creating a beautiful rainbow.
Chromatic Pool is part of the largest geyser field in the world.
Grotto Geyser is a lesser-known steam engine.
Old Faithful leaps high, but it's biggest asset may be its reliability, always showing up on time.
