Karpa Island rises from the maritime waters of the Shumagin Islands in this topographic study of the Alaska Peninsula region. Located within the Aleutians East Borough, the landform is defined by distinct elevation contours that reach a central peak, illustrating the steep coastal topography characteristic of this archipelago. The surrounding expanse is primarily maritime, divided by the Public Land Survey System grid lines for t54s r71w and t54s r70w. This survey is focused on the uninhabited landmass, providing a clear record of the shoreline and elevation before further natural or environmental shifts. It serves as a specific reference for the geographic boundaries and hydrography of this isolated portion of the Shumagin group.
