Thermophilic variety Temperature, water chemistry, and stream flow affect what thermophiles grow in a location. They can be bacteria, viruses, or other microorganisms.

An #outflow channel from a #hotspring in the #SnakeRiver #thermal area, showing a mix of thermophiles.

This requires a ten-mile roundtrip #hike from #SouthBoundary, or five-mile #backpacking. You ford the Snake once in each direction.

Hot spring at Snake River A backcountry hot spring. Pro tip: only dip where hot water flows into cold water, and only if you've checked with the park about Naegleria fowleri, a brain-destroying amoeba.

Within a half-mile (or km) of #SnakeRiver #ford you will see three #hotsprings from the #SouthBoundary #Trail. This is the second.

You can see two #backcountry #geothermal basins on 10-mile day hike, or start #backpacking itinerary.
