About this map

Pedro Bay sits on the northern shores of Iliamna Lake, serving as a critical point of access for this portion of the Lake and Peninsula Borough. The landscape is defined by the transition from the high elevations surrounding Knutson Valley down to the complex coastline of the lake. Transportation in this remote area is anchored by the Pedro Bay Airport, which connects to the settlement via Airport Road and Bay Road. These few corridors represent the primary human imprint on a terrain otherwise dominated by significant water features and islands.

Waterways like Knutson Cr flow through deep valleys to reach the lake, while the eastern shoreline is marked by the sheltered waters of Lonesome Bay and Pile Bay. Notable landmarks such as Lonesome Point and Porcupine Island provide clear navigational markers for those traversing the lake. The presence of Dumbbell Lake and the navigational hazard of the Big Chutes further illustrate the maritime and wilderness character of this Alaskan interior region during the early twenty-first century.
