The Valley Floor at Ten Thousand Smokes
We hiked down to the valley floor, a vertical drop of 800 feet, during our visit to 10,000 smokes. It was a worthwhile trip, and as the weather cleared we were able to get pretty impressive views of the valley. There are deep fissures in lots of places in the terrain from the volcanic activity and the moving of the earth. For more details on this area, click on the Wikipedia link below.
