2017 Map of Tyonek B-8 SE

About this map

Nagishlamina River flows through this high-elevation terrain on the western side of the Kenai Peninsula, marking a landscape defined by dramatic glacial activity and steep drainage basins. The presence of the Harpoon Glacier in the northeastern corner of the sheet highlights the ongoing geological processes that shape this wilderness area. Surveyed for the National Elevation Dataset, the map reveals the complex topography of the T15N R19W and T14N R19W townships, where extreme relief and vertical descent characterize the river's course. Unlike lower-lying coastal areas, this region remains focused on natural hydrology and glacial flow, with no marked settlements or infrastructure, offering a pristine record of the high-country drainage systems as they existed in the early twenty-first century.
