Signal Hill, a high peak of the James River bluffs one‑half mile north of State highway No. 7 on Southeast 1/4 i6‑146‑64. 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.
