The Canada/United States of America border defines the southern edge of this topographic survey, marking the thin line between the Washington backcountry and British Columbia. This high-altitude terrain is characterized by a dense network of seasonal creek beds and drainage channels that carve through the landscape, feeding into larger basins just outside the sheet's boundaries. The map provides a precise look at the 2017 drainage patterns and land contours near the international boundary, an area where the topography dictates the flow of local hydrology and the placement of remote access routes along the border corridor.
