The Henderson Monument is located on the northwest quarter of the southeast quarter of section 14, Beaver. It is a granite shaft on a base of similar material. This is erected in memory of Mrs. R. H. Henderson, her two daughters, Jehiel Wedge and Eugene White, who were killed during the Indian Massacre. It marks the spot where the bodies of these people were buried. Some time after the Massacre, Fred Thies accidently shot himself in the Minnesota bottoms. He was buried at the same spot and his name likewise appears on the monument.
