abstract
The Big Spring at Thermopolis is roughly 5 m in diameter, with a 4 m outflow channel 150 m in length to the first cooling pond. The mineral-rich 52-54°C water flowing from the spring is the result of groundwater flow from the Owl Creek Mountains to the south, intersecting an east-west fault-line beneath the Thermopolis valley. Water and microbial samples have been collected on a semi-regular basis from August 2008 to present. We describe microbial communities, the microbe types within them, and how they change “downstream” at 11 sites from the inflow to the outflow, and 5 sites beyond the cooling ponds. The main spring supports a multitude of pigmented bacteria: a thin green layer covering a thicker reddish-brown layer, a growth pattern typical of cyanobacteria; purple and green filamentous bacteria; and yellow spongiform mats around the edges. There is a clear distinction of morphologies of the microbial communities with distance from the outflow. In the outflow channel the morphology changes from green to white filamentous and biofilms near the outflow, to algal mats with abundant trapped gas bubbles, to spongiform mats and vertical columns pushed upward by trapped gas bubbles within the mat, at the edge of the cooling pond.
