Mud Geyser

Nature
7
In the late 1800s, Mud Geyser erupted every few hours, spewing muddy water 50 feet or 17 meters into the air, but by 1927 eruptions no longer occurred. Half a century later, a swarm of earthquakes shook the area, and soil temperatures skyrocketed, killing many of the trees that surrounded the pool. Around the turn of the 21st century, violent steam vents hissed forth, and their large craters opened wide enough to swallow fallen logs. Whether Mud Geyser will erupt again is unknown, but the area remains changeable.
