"Streamlet branchings of the abnormal type found in the area in and about the Pomperaug Valley. a and i, streamlets controlled by two sets or airs of fault planes. b and c, streamlets preponderantly controlled by a single series of parallel planes; d, f, and h, by a nearly rectangular system of fault planes. e and g, streamlets indicating that neighboring streamlet branchings have been controlled by the same fault plane. The side streamlets of g indicate control by a second series of faults." -Walcott, 1901
