G. Signal Hill:

A high peak of the James River bluffs one‑half mile north of State Highway 200 on Southeast 1/4‑16‑146‑64. It is from this point the Indian smoke signals were sent up. The U.S. Geological Survey erected and operated a signal tower at this point in the fall of 1934. The tower is still standing. The land is owned by Sigvart Holland, Juanita, North Dakota
