2014 Map of Mount Redoubt OE N

About this map

The international boundary of Canada / United States of America defines the southern edge of this remote mountain study, where the high country of British Columbia meets the northernmost reaches of Washington. This 2014 survey focused on the hydrography and topography of the Chilliwack River Valley area, documenting a complex network of alpine streams and drainage basins before they cross into Whatcom Co. The map captures a landscape defined almost entirely by its natural drainage patterns, offering a precise look at the headwaters that feed the regional watershed across the 49th parallel. It serves as a modern baseline for the transboundary wilderness, where no major roads or settlements interrupt the watershed, highlighting the isolation of this portion of the Fraser Valley Regional District.
