1. Old Delta Sediments Marker, missing
Inscription. Diverted into this valley by lava flows, the Bear River deposited a huge, mostly red clay delta here where it entered a vast inland sea that covered much of Utah.
About 14,500 years ago , its shoreline suddenly went down about 80 feet following an enormous discharge into the Snake River. From then on, it gradually receded to become the Salt Lake. Bear River then had to cut through and erode its old delta, forming the steep sides and gullies you see here today.
 
Erected by Idaho Department of Transportation. (Marker Number 432.)
