Comments:
Riprap not very evident on banks, but VW below Rte. 110 covered in honeysuckle: unclear if it is riprapped or bedrock, but assumed to be heavily riprapped. Rte. 14 bridge at base of segment had Irene debris lodged into girders 18' high, but did not appear that terrace on RB (old Crawford Autoland) had been accessed. Deep entrenchment of this segment may be related to emptying of glacial Lake Hitchcock rather than historic incision, which may make this segment a subreach (B4c vs. overall reach type C4) rather than a stream type departure (C-->B) as it is characterized here. Regardless of this distinction, plane bed features and limited planform adjustments are related to the entrenchment.
