Port Clarence Coast Guard Station — Port Clarence, United States

Port Clarence Coast Guard Station occupies a remote spot on the Seward Peninsula in western Alaska, at an elevation of just 10 feet on the low coastal ground facing the Bering Sea. Its single asphalt runway of about 4,497 feet reflects the airfield's origins as a support site rather than a commercial airport. This is one of the most isolated corners of the United States, far from the road network and close to the narrow waters separating Alaska from Russia. The KPC code identifies the field within aviation databases, marking a facility whose role has been tied to Coast Guard and support operations along Alaska's exposed western coastline.
