"Various data have led some researchers to hypothesize that hydrothermal venting is active on the floor of Crater Lake and that it contributes significantly to the chemical and physical properties of the Lake. Searches in the southern basin using remote-controlled submersible and a one-person submarine failed to identify and hydrothermal flows, and elevated temperatures measured are consistent with normal groundwater temperatures. An alternative explanation of the data is the possibility that cold, mineralized groundwater seasonally seeps into the south basin of the Lake. This seepage could be facilitated by the Chaski Bay slide which extends from the south caldera wall into the south basin. This alternative hypothesis is proposed in view of the apparent absence of some features normally found associated with hydrothermal systems."
