Puget Sound Electric Railway Puget Sound Electric Railway The Puget Sound Electric Railway was an interurban railway that ran for 38 miles between Tacoma and Seattle, Washington in the first quarter of the 20th century. Portions of the right-of-way still exist as multi-use trail through Milton, Washington, as well as from Pacific to Tukwila, Washington. The PSE began operations on September 25, 1902 with a line that started in downtown Tacoma, ran along Pacific and Puyallup Avenues, followed the course of present day Pacific Highway through Fife and to Milton, turned southeast towards Puyallup and paralleled the path of today's SR 167 through Pacific,
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,
