About Earthquake Rock
Located at the bottom of the rapid and directly in the channel is a large rock that shook loose from the canyon and landed here after an earthquake.
How to run Earthquake Rock
At medium and high flows you can run right fairly easily for the entire length of the rapid. As the water drops, the right side begins to get choked off with boulders forcing a center entrance and a more demanding move to get around earthquake rock. The water is swift so while the move is usually pretty easy, you need to be paying attention. At low water the channel to the right of the rock is tight, so you might want to consider going left of it which is pretty easy to do.
In this low water photo, you can see how the right side gets blocked by boulders. Once you clear these, keep working right. Photo by Idaho River Journeys.
