From Iowa’s HP I drove to the Black Hills for the night. I was lucky to get a campsite at Sylvan lake since it was full with a group, they let me have the only open site. In the morning I hiked to Harney Peak. I was the only one there for some time when a man (another hper) and his two daughters arrived. Nice lookout tower with living space below and in separte buildings nearby. Took pics then hiked down. Started the drive to WA, overnighting in Bozeman.
