Pink Cone Geyser, Cone geyser in Lower Geyser Basin, Yellowstone National Park, US.
Pink Cone Geyser is a cone geyser in Lower Geyser Basin, Yellowstone National Park, distinguished by its pink and reddish coloration. The color comes from manganese and iron oxide deposits that have accumulated on the siliceous sinter cone over time.
The geyser's eruption pattern changed dramatically following an earthquake in 1983. Its previous twice-daily frequency shifted to less regular intervals, altering the dynamics of this thermal feature.
Scientists and park visitors document the geyser's behavior through photographs and data collection, contributing to geological research in Yellowstone National Park.
Eruptions occur at intervals of about 9 to 22 hours and last roughly 1.5 to 2 hours each. Steam and gurgling sounds build up before each eruption, which help signal when the geyser is about to erupt.
Water in this geyser reaches temperatures around 91 degrees Celsius, making it one of the hotter thermal features in the area. This intense heat powers the regular eruptions and the characteristic steam emissions observed here.
