You can't miss this one when you are coming up on it. There is a big house on the bluff on river right overlooking the rapid. Also a huge boulder, and some smaller ones, right there too. Hence the names. Some folks call it House Rapid and some just call it Big Rock, but whatever you want to call it, all agree that it is the best rapid in the stretch. Good playspot at the right levels, which most agree would be between 3.5 - 5 feet on the gage. The most popular surfing spot is just below the big rock, but there are other good but smaller play spots in this area.
At the river right chute of the big rock there is a shallow rock right in the middle of that wave, so it is best not to be bottom side up there. Other than that hazard, any swims in this area will generally be pretty easy to recover from.
