2017 Map of Castle Peak OE N

About this map

The international border between Canada and the United States of America defines the lower boundary of this high-altitude landscape. This 2017 survey focuses on a remote, largely undeveloped area within the British Columbia Cascades, specifically the southern reaches of the Fraser Valley Regional District. The map displays a complex network of alpine drainage systems and seasonal streams that flow southward toward the border, highlighting a landscape defined by sharp elevation shifts and natural watersheds rather than human settlement. Because it covers a region where the two nations meet along a rugged mountain crest, the survey serves as a vital record of cross-border topography in a place where modern infrastructure and roads are notably absent.
