Naboko of Kamachatka Volcanology Station 1938-1939. Spectral analyses of rendered gas by-products from a lava flow from Biloikai crater are non-quantitative and reported as detects only. Fumarole gas analyses are also from Biloikai crater and consist of H2O and HCl only. Other Description: Naboko, C.I.
