Brightly-colored deposits of elemental sulfur surround fumarolic vents on the NW side of the central cone of Mendeleev volcano, in the southern Kuril Islands. These fumaroles are located within several craters where the central cone meets the inner caldera wall. Hot springs occur on the NE flank and along the NE coast, where the Goriachi-Pliazh geothermal field is located.
