Boulder Field

A wide section of river where a fence-like jumble of rocks cuts across the river. The entrance to the Boulder Field begins with Mother Rock, the largest boulder in the rapid and it's usually passed on the left. Higher flows turn Mother Rock into Mother Hole.

At moderate to high flows boaters usually run left of center over the waves while dodging pour overs.

At low flows boaters typically navigate down to the fence-like rock jumble ("The Bermuda Triangle") then move to the center of the river to pass through two large guard rocks called the Horns (or the Fangs). There are two commonly used channels to get to the fence-like rock jumble: weaving through the boulders following a line just left of center, or in very low water conditions along the left shore. At the jumble boaters paddle across the river just upstream of the jumble and slip through the Horns/Fangs with a turn to the left. Beware of Hemorrhoid rock below the Horns/Fangs – it splits the channel below Horns/Fangs in two, the left channel being the rockier of the two. At low-moderate flows, there is a large safety eddy below Hemmorrhoid on river left. At extreme low flows a small partially submerged rock appears just above the Horns/Fangs: rafters have to pick-up enough momentum to slide up and over the rock and into the Horns/Fangs. Boulder Field can be scouted from the road.
