This article focuses on “Whoop-Up Country” in the Canadian/American West, analyzing a series of multi-layered cartographic texts through the lens of bordertextures. While the meaning of the Whoop-Up Trail may have faded into obscurity, the hidden histories, geographies, and knowledges of this border zone have survived and continue to resurface in the cultural imaginary. Zooming in on texts by Paul F. Sharp, Wallace Stegner, and Thomas King, the analysis carves out the multi-dimensional (hi)stories of the Canada-US border that account for the complexity of North American borderlands.
