7.5 Channel Adjustment Processes Narrative  
  Extreme aggradation which has led to multiple thread channels. Logging practices have caused debris jams in channel that are holding back sediment and causing a change in elevation. Channel is now cutting through the deposition as evidenced by headcuts at the debris and higher banks downstream of debris. Channel is in F-II because it is actively incising. Extreme planform due to braiding condition and large depositional features.
