Schematic model showing a cross section of Old Faithful's plumbing system as determined from seismic studies. The red circles (t0-t3) show the location of the tremor source over time, and how the tremor source migrates upward prior to an Old Faithful eruption. Times between red circles are based on a 93-minute eruption interval.

A brook floater filter feeding as it is anchored into the sediment of a stream bottom. Habitat loss is a long-recognized problem for many endangered species, and the brook floater is no exception. In-stream alterations that change flow and alter sediment loads can affect downstream locations where freshwater mussels live.
