The Dvoinoi (Sugar) geyser is one of nearly 30 found in the "Valley of Geysers," a major geothermal area along a 4-km-long valley near the eastern margin of the Geysernaya caldera at Kamchatka's Uzon volcano. High heat flux near the eastern ring faults of the caldera produces active geysers, boiling hot springs, and mud pools.
