Motorcycle Ride 4 - Arrowrock Dam Idaho
The fourth photo in the series of the Arrowrock Dam still in an unfinished state. The Dam's opening ceremony was held on October 4, 1915 and was the highest dam in the world at the time at 348 feet. The dam is located east of Boise ID, damning the South and North forks of the Boise River. This may have been around the opening ceremony as it was still under construction possibly 1915-16.
