2017 Map of McCarthy B-3 SW

About this map

The Saint Elias Mountains dominate this high-altitude landscape in the Unorganized Borough, where extreme topography dictates the boundary between protected wilderness areas. The map reveals a transition between the Wrangell-Saint Elias National Park to the north and the Wrangell-Saint Elias National Preserve to the south. This distinction is significant for land use and resource management within the largest national park system in the United States. Glacial activity is the primary architect of the terrain here, most notably seen in the massive Twaharpies Glacier which flows through the northern reaches. High-relief summits such as Celeno Peak, Ocypete Peak, and the jagged spires known as The Twaharpies stand as permanent landmarks above the moving ice. The survey provides precise contour data for these remote peaks, illustrating the complex drainage patterns and ice fields that remain largely untouched by permanent human settlement.
