There are signs indicating South Breitenbush Gorge 1 mile. We walked about 2 miles and didn't see anything that looked like a gorge. We did find a log across the river that had hand rails attached and a side trail with a hand lettered sign "Emerald Forest Trail". We crossed the log bridge, sat on the end this same log, watched the river and ate lunch. There was some speculation that the trail continued to the community of Breitenbush. We were far enough from the main trail that didn't see a couple of bicycles that passed while we lounging about. I am sure they didn't see us either.
Along the main trail there has been quit a bit of blow down and some mud sliding. (The trail is in good shape below the middle trail head.) On our way back to the car at a place where a few trees had fallen over I noticed a sign on one of the downed trees indicating the South Breitenbush Gorge. There are logs on the ground over a muddy area. Walking down these logs brings one right to the edge of the river. The river goes through a narrow chasm at this point. The water rushes and dances over small falls and around outcroppings. Even though the scale is small it is quite impressive and worth the walk. When we returned to where the middle trail head connector joins the main trail we decided that we would go up to the road. Then we walked back up the road to the car. We had climbed over several downed trees above that point and found no pleasure in repeating the experience.
We did see White Iris along the trail as well as several other old friends (wild flowers). We have found White Iris in a few other places, such as Coffin Mountain, and along the upper McKenzie River.
