Valley of the Geysers

A small section of Dolina Geyserov. Unlike one may think geysers are pretty quit. No hissing sounds, only
the sound of water falling back on the rocks. The sulfurous smell is everywhere. The gray and yellow rock faces on the right of the valley are 
actually Kikhpinych volcano, the Zheltaya Sopka, or 'yellow hills'.

Yellow formations of the Malakhitovy Grot, a pulsating spring.

Bubling mud pots are common in the valley of the geysers.
