The highest point between Chehalis and South Bend at the crest of a divide southeast of South Bend in east central Pacific County is called Pluvius. W. C. Albee, when superintendent of South Bend branch of Northern Pacific Railway, devised the name because of the heavy rainfall in the region. The name is an alteration of the Latin word Pluviosus which has the significance of heavy rains or precipitation. The writers of the Railroad List noted that the name was given “…due to the fact that it rained incessantly during the construction of the line.”
