Big Cub Geyser

Description

The Lion Group consists of four geysers: Lion, Lioness, Big Cub, and Little Cub, which are all connected underground. Of these Lion has the largest cone and eruptions. Active phases normally occur each day. Eruptions of Lion Geyser can be as high as 50 feet (15 m) for 1 - 7 minutes and are often preceded by sudden gushes of steam and a deep roaring sound, hence the name Lion.
