Kettle - B) Banning State Park to Sandstone (2.8 or 4.3 miles) (MN)
Reasonable beginner flow.
Quarry Rapids is formed by a broken-down dam/rubble-field, creating a class II with sharp boulders churning the flow. A wide smooth wave normally forms at the top of this drop. Bottom left of the drop (at higher levels) tends to form a somewhat sticky looking hole, while the right is a fine flush into great swirls in the pool below. Many cautious/timid boaters forego any play here over concerns about flipping onto the shallow rocky rubble.
