Comments:
Very variable- some sections incised, toppling trees; other areas blown out, widened/aggraded. Cross section does not reflect extremes. 300' section of bedrock gorge by Dartt Hill Rd (central portion of segment) is a 12.8 ft bedrock constriction (the bridge here provides no constriction) but was not segmented out due to short length. Additional grade controls (two more near Dartt Hill, one at US end of segment) limit incision and provide some stability for reach as a whole.
