Previous postglacial rebound models applied to this area feature ice loading histories that lack ice cover in Puget Sound and in some cases even southern Vancouver Island. Rapid, late Pleistocene uplift is indicated by sparse relative sea level data from eastern Vancouver Island. This rapid uplift cannot be fit unless a global ice history model previously applied to the region is refined and implies a mantle viscosity of 10^19 Pa s or less. A more detailed ice history reconstruction, when applied to tilting of late Pleistocene proglacial lake shorelines in the Puget Sound area, indicates a range of acceptable values of mantle viscosity and lithospheric thickness, although lithospheric thicknesses of only a few tens of km and mantle viscosities £ 10^20 Pa s seem to be a robust outcome. The observed rapid uplift and inferred low mantle viscosity values imply that postglacial rebound was essentially complete soon after deglaciation, suggesting that Holocene sea level variations in south coastal British Columbia are primarily a consequence of hydro-isostasy (ocean water loading owing to global sea level rise) combined with potential plate interaction effects related to the subduction of the Juan de Fuca plate. Additional high-resolution late Pleistocene and early Holocene relative sea level data are needed from coastal British Columbia and Washington state to better understand the Earth's response to the waning phases of the Cordilleran ice sheet and global sea level rise. These data can be obtained by dating marine/lacustrine transitions in cores recovered from isolation basins at a range of elevations above and below present sea level.</style></abstract></record></records></xml>
