Named after Olequa Creek, circa 1872, by General J.W. Sprague, two competing theories of the Cowlitz Indian word, Olequa, exist. One hypothesis is considered to come from a vague association of the term "cametze", translated to mean "where the salmon come to spawn". A second theory suggests the name came from the sound associated with a nickname of an elder, well-known Cowlitz tribal member, "Old Laquash".[3][4]
History
The community originally was situated on a main line of the Northern Pacific Railroad.[3] A post office called Olequa was established in 1875, and remained in operation until 1912.[5]
