2018 Map of Seward D-6 SE

About this map

The Placer River Valley serves as a central corridor for transportation and glacial drainage through the Chugach National Forest in this 2018 survey. The landscape is defined by the convergence of major waterways, including the Twentymile River, Placer River, and Portage Creek, which flow into the north end of the Pacific Ocean inlet. The Seward Highway and the Portage Glacier Road provide the primary access through this complex terrain of wetlands and glacial outflow. Detailed mountain features like Explorer Glacier and the seasonal Iditarod National Historic Trail (INHT) routes illustrate the intersection of modern recreation and historical transit paths. Small inland water bodies such as Luebner Lake, Airstrip Pond, and Alder Pond dot the marshy lowlands, providing specific landmarks for those navigating the valley floor between the high ridges of the Anchorage Municipality and Kenai Peninsula Borough.
