The Yellowstone River is along the upper half of the photo with flow to view left. The Rosgen project was in view upper right along the near side where it appears straight. Armstrong's part of Spring Creek is along the lower half of this view, and DePuy's part is off this view to the left. The discussion is not about the Rosgen project, and the dam was not built as shown. Note the Root Wads that were used in Rosgen's constructed bank.
