View toward the mainland from the center of White Island, a volcanic island off the coast of New Zealand's North Island, in the Bay of Plenty. Most of the island is effectively a volcanic crater, full of boiling mud and fumaroles.
This spectacular and colorful valley in Yellowstone, Wyoming is the Grand Canyon of the Yellowstone River. Two large waterfalls occur along this stretch of the river - Upper Falls and Lower Falls. The rocks of the canyon include rhyolite lava flows, rhyolitic volcanic tuffs, and some sedimentary deposits - all are geologically young and date to the Quaternary. The yellows, pinks, reds, and oranges indicate the presence of hydrothermally altered rocks. Hydrothermal metamorphism refers to the intense alteration by superheated groundwater. Yellowstone has over 100,000 hydrothermal features in the form of hot springs, geysers, fumaroles, frying pans, and mudpots, so hydrothermal alteration is fairly common in the area.

This fumarole was drilled as part of a geothermal energy project. The generator building we passed by later looked pretty tiny.
