Historical Significance:
The Historic 35th Parallel marker remembered the explorers who followed the path of the 35th parallel across northern Arizona. This route has been journeyed by Indians, missionaries, trappers, and military men. Hell Canyon Bridge was a large‑scale steel truss bridge built in 1954 to span this historically important transportation route north of Prescott.
The plaque read, “Historic 35th parallel / For ages a route traveled by Indians – Missionaries – Trappers / U.S. Army survey in 1851 by Captain Lorenzo Sitgreaves / In 1854 Lt. A. W.
