Puget Sound Shore Railroad Puget Sound Shore Railroad The Puget Sound Shore Railroad and successor Northern Pacific and Puget Sound Shore Railroad built a branch line of the Northern Pacific Railroad between Puyallup and Seattle, Washington, U.S., and partially constructed a line around the east side of Lake Washington to Woodinville. After Congress chartered the Northern Pacific Railroad (NP) in 1864, the communities along Puget Sound competed to be its Pacific terminus. Tacoma, about south of Seattle, became the winner in July 1873, when the NP, then building north from Portland, selected it. Seattle businessmen immediately incorporated the Seattle and Walla Walla Railroad and
Puget Sound faults Lowland. In particular, to the southeast of Mount St. Helens and Mount Rainier they reflect a regional pattern of NNW oriented faulting, including the Entiat Fault in the North Cascades and the Portland Hills and related faults around Portland (see QFFDB fault map). Yet the SHZ and WRZ may be integral to the regional geology of Puget Sound, possibly revealing some deep and significant facets, and may also present significant seismic hazard. The WRZ and SHZ are associated with the "southern Washington Cascades conductor" (SWCC), a formation of enhanced electrical conductivity lying roughly between Riffe Lake and Mounts St. Helens,
