Notes

Arsenic (As), mercury (Hg), and carbon dioxide (CO2) all appear in anomalously high concentrations near the hot springs and at the junction of the Fumarole Valley and the HSBV. This indicates either that Hg is being lost from a reservoir due to boiling and steam loss, probably northwest of the junction, or erosion has carried these elements in sediment from the higher elevation manifestations. The presence of such volatiles in sediments indicates a potential for close proximity to an underlying near-boiling resource. Anomalous measurements of mercury and arsenic in soil are consistent with the presented conceptual model and suggest that an upflow near the fumarole may extend over 1000 m to the southeast.
