Dickison Mounds, Peoria County, Illinois 
lot of 16, longest 5-3/8 in.

The Dickison Mounds are located north of Peoria, Illinois, overlooking Lake Peoria.  The mounds were named for J.B. Dickison, whose family farm was built on top.  This group consisted of 12 mounds, of which the southern most was destroyed to build a construction facility.  The debris from the mound was used for fill for the construction of Illinois Route 29.  These cache blades were found in the debris during the highway construction.
