2017 Map of Kenai D-6 SW

About this map

Lake Clark National Park occupies the northwestern corner of this 2017 survey, where high-elevation contours mark the edge of the Chigmit Mountains. This landscape is defined by the complex hydrography of the Big River basin, showing a network of glacial meltwater channels and braided river systems. The North Fork Big River flows southward through the center of the sheet, eventually meeting the S Fork Big River in a wide valley of wetlands and shifting gravel bars. Tributaries like Bachatna Cr and Bachatna Creek descend from the eastern slopes, illustrating the transition from steep mountain terrain to the broad, hydrologically active lowlands. This map provides a detailed record of water drainage patterns and protected wilderness boundaries in the Kenai Peninsula Borough before recent changes in glacial recession and alluvial deposition.
