The contemporaneous Yakima War may have been responsible for some events of the Puget Sound War, such as the Battle of Seattle, and it is not clear that the people of the time made a strong distinction between the two conflicts. The Puget Sound War began over land rights and ended in a cloud of controversy surrounding the hanging of Leschi. The catalyst of the war was the Treaty of Medicine Creek of 1854.

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,
