14 MAY 2019: A noisy geyser in Yellowstone National Park has roared back to life after three years of quiet. Ledge Geyser is the second-largest geyser in Norris Geyser Basin after Steamboat and shoots hot water at an angle up to 125 feet (38 metres) into the air. .

The Billings Gazette reports the geyser shoots a distance of 220 feet (67 metres).

Yellowstone geologist Jeff Hungerford says Ledge Geyser is noisy because its water and steam must pass through a narrow opening in the ground.

Yellowstone has 1,300 thermal features and 500 geysers, more than anywhere else on Earth. Some geysers such as Old Faithful are predictable but most, like Ledge Geyser, erupt erratically.
