Traverse City MI explains the name for the High Rollaway, officially the Manistee River High Banks Rollaway:
The high river bluff is the reason for the area’s unusual name. At the turn of the last century, lumbermen needed inexpensive ways to transport timber from the forest to the sawmills and wide-flowing rivers like the Manistee were the answer. Steep banks were used to “rollaway” the logs in a thunderous avalanche to the water where they floated to the mills. Unfortunately, the practice quickly stripped the vegetation from the river banks and, by the time the lumbermen moved on, eroding sand was clogging and narrowing the rivers. In the last 20 years, efforts have been made to stabilize the Manistee River High Banks with fieldstone terraces and replantings. The observation platform was installed in 2001 so visitors could enjoy the stunning view without damaging the fragile system.
