Inscription.  Until about 28,000 years ago, Bear River used to flow northwest from here through Portneuf Canyon into Snake River.

Then these lava eruption blocked that route, diverting Bear River south into what now is Salt Lake. At that time a large inland sea -- known as Lake Bonneville -- covered much of Utah. Additional water from Bear River helped make it overflow into Snake River before a change in climate dried it up about 8,000 years ago.
 
Erected by Idaho Department of Transportation. (Marker Number 220.)
