Rift Geyser.

"If you see a crowd at Grand Geyser and the pool looks full, wait a while. You might get lucky and see the tallest predictable geyser in the world erupt. A classic fountain geyser, Grand erupts with powerful bursts rather than a steady column like Old Faithful. An average eruption lasts 9-12 minutes and consists of 1-4 bursts, sometimes reaching 200 feet."

Wave Spring.

The clouds are starting to shroud the sun. Now that's a pitty, the colors won't come out very well in my photos. Regardless, I soldier on.

Beauty and Chromatic Pools. "Beauty Pool shows its brightest colors when its water is hottest. When the water is cooler, as it has been recently, earth-toned thermophiles thrive. Beauty is closely related to neighboring Chromatic Pool. During periodic energy shifts, the level of one spring rises as the other descends."
