1973 Map of Si Merrell Slough

USGS Topo · Published 1976

About this map

Outlet Marsh Waterfowl Production Area dominates the northern landscape of this borderland survey, marking a vital wetland habitat along the international boundary between the United States and Canada. The geography is defined by a network of seasonal water bodies and drainage systems, including Merrell Slough, Willard Slough, and Outlet Creek, which suggest a landscape governed by the ebb and flow of northern plains hydrology. To the south, the topography shifts toward the prominent elevation of Square Butte, providing a distinct navigational landmark in an otherwise prairie environment.
