1986 Map of Tyonek A-1 SW

About this map

Point Possession marks the northern tip of the peninsula where the waters of Cook Inlet meet the Turnagain Arm. This mid-1980s provisional study details a significant transition zone where the Municipality of Anchorage meets the Kenai Peninsula Borough boundary across the marine channels. The landscape is dominated by the protected coastal reaches of the Kenai National Wildlife Refuge and the Kenai Wilderness, showing a terrain largely defined by its natural state. Small inland water bodies like Diamond Lake and Cook Lake sit just behind the shoreline, while the expansive mudflats of Chickaloon Bay and the distant profile of Fire Island illustrate the dynamic tidal environment of this Alaskan maritime region.
