Geyser
Yellowstone is the largest geyser locale, containing thousands of hot springs, and approximately 300 to 500 geysers. It is home to half of the world's total number of geysers in its nine geyser basins. It is located mostly in Wyoming, USA, with small portions in Montana and Idaho. Yellowstone includes the world's tallest active geyser (Steamboat Geyser in Norris Geyser Basin), as well as the renowned Old Faithful Geyser, Beehive Geyser, Giantess Geyser, Lion Geyser, Plume Geyser, Aurum Geyser, Castle Geyser, Sawmill Geyser, Grand Geyser, Oblong Geyser, Giant Geyser, Daisy Geyser, Grotto Geyser, the Fan & Mortar Geysers, & the Riverside Geyser, all in the Upper Geyser Basin which alone contains nearly 180 geysers.
2010 Mount Meager landslide
Mount Meager, located north of Vancouver, is a peak of the Mount Meager massif. This is a group of coalescent stratovolcanoes and the largest volcanic centre in the Garibaldi Volcanic Belt. It comprises about of eruptive rocks that were deposited during four distinct eruptive periods, the first beginning 2.2 million years ago. During the present period (beginning 150,000 years ago), it has erupted more than five times, producing ash falls, pyroclastic flows, lava flows and lahars. The only identified Holocene eruption was in about 410 BC and created a diverse sequence of volcanic deposits well exposed along the Lillooet River. This is the most recent major explosive eruption in British Columbia, as well as the largest known Holocene explosive eruption in Canada.
