Tarr Inlet is a deep, glacially carved fjord located in the West Arm of Glacier Bay National Park & Preserve in Alaska. This dramatic saltwater inlet is dominated by the towering faces of the Margerie and Grand Pacific glaciers at its northern terminus, which create a stunning backdrop of floating ice and steep, mountainous terrain. The water is profoundly influenced by glacial melt and significant tidal exchanges, creating a dynamic marine environment rich in nutrients and life. The inlet's geography, with its deep central channels, submerged reefs, and protected coves, supports a diverse fishery that is intrinsically linked to the powerful tidal currents and the seasonal migrations of Pacific salmon.
