when was the last time yellowstone park erupted
Yellowstone Caldera Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption.[13][14] The most recent lava flow occurred about 70,000 years ago, while a violent eruption excavated the West Thumb of Lake Yellowstone around 150,000 years ago. Smaller steam explosions occur as well: an explosion 13,800 years ago left a 5 km (3.1 mi) diameter crater at Mary Bay on the edge of Yellowstone Lake (located in the center of the caldera).[15][3] Currently, volcanic activity is exhibited via numerous geothermal vents scattered throughout the region, including the famous Old Faithful Geyser, plus recorded ground-swelling indicating ongoing inflation of the underlying magma chamber.
Yellowstone (U.S. TV series) Principal photography for the series began in August 2017 at the Chief Joseph Ranch in Darby, Montana, which stands in as the home of John Dutton. Filming also took place that month near Park City, Utah. The production used all three soundstages at the Utah Film Studio in Park City, which is a total of 45,000 square feet. The building also houses offices, editing, a huge wardrobe department and construction shops. By November 2017, the series had filmed in more than twenty locations in Utah, including the Salt Flats and Spanish Fork. Additionally, filming also took place at various locations in Montana. Production was reportedly set to last until December 2017.[29][30]
