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,
