Nutcracker is formed where the river flows over a rock fence then constricts tightly whilst steepening, being constrained by a vertical cliff on the right slide and downstream a large round boulder on the left. Boaters arriving at the horizon line are often greated with no better clue as to a line than a cloud of mist rising from below. However this rapid turns out to be quite forgiving, though wonderfully boisterous. People generally enter center through right of center through a gap in the submerged rock fence then just head center, paddle hard and hang on! The rapid is composed of breaking waveholes and staying upright and straight is the main problem. The rapid empties into a deep and slow pool at normal flows.
