Notes

The US Department of Agriculture conducted the initial geochemical analysis of the Chena Hot Springs in 1917. Two springs were sampled and the analysis indicated sodium carbonate type waters, consistent in both springs. Low calcium and magnesium concentrations were measured, with elevated levels of silica and sulfate. Surface fumarole gases were tested with a flame to indicate carbon dioxide concentration. Algal growth was present in vicinity of the hot springs but not in the nearby creek. Sulfur deposition was also observed near several hot springs. The overall flow of the hot springs was measured at 220 gal/min. Warm seepage was noted 200 yards SE of the uppermost spring.
