Comments:
Short segment which is distinguished from downstream Segment A by degree of vertical stream type departure (C to F). Valley confinement broadens in this segment downstream of the bedrock gorge (Segm C). Chiselville Rd passes through the LB corridor causing a minor human-caused change in valley width (St 1.5); however, this road is only slightly elevated above the floodplain. Historic resources (Beers, 1869; Walling, 1856; Child, 1880) depict mills and industrial activity in Chiselville along the LB corridor of this segment. A diversion channel (from historic impoundments in Segment C) used to lead to a "Chisel Fact." as shown on the Beers map, with water returned to the Roaring Branch channel just downstream of the Arlington-Sunderland town line (Segment A). Today land use in the LB corridor is residential in nature. Two, mostly healed (vegetated) mass failures were observed along the steep RB valley wall.
