Wrangell Mountains dominate this high-altitude landscape in the Copper River Census Area, where glacial movement continues to carve the alpine terrain. This modern survey illustrates the critical boundary between the Wrangell-St. Elias Wilderness and the Wrangell-Saint Elias National Preserve, a division reflecting decades of conservation management in the Alaskan interior. The southeastern corner is marked by the presence of the Nabesna Glacier, providing a detailed view of its current extent and the surrounding moraine and ice-field patterns. The absence of roads or permanent structures underscores the isolation of this protected wilderness, where navigation relies entirely on natural landmarks and elevation contours.
