July 2014 Hydrothermal Assessment of Proposed Old Faithful Inn Sewer Line Routes, Yellowstone National Park
Heasler H and Jaworowski C. 2014. July 2014 Hydrothermal Assessment of Proposed Old Faithful Inn Sewer Line Routes, Yellowstone National Park
Park management plans to replace the existing Old Faithful Inn forced sewer line between the lift station and the existing gravity portion of the sewer line in the Myriad Group. This brief report summarizes hydrothermal and geologic conditions encountered on 24 July 2014. All proposed sites are within an active hydrothermal system as defined by hydrothermally altered ground, hydrothermal deposits, and elevated subsurface temperatures. Fifteen additional subsurface temperatures measured within 4.6 m (15 feet) of the lower service road at 85 cm (33.5 in) depth ranged from 27.1 to 59.9 degrees C (80.8 to 139.8 degrees F). The maximum measured carbon dioxide concentration was 3.8%.
