Glacier bay is a broadly open fiord between the Fair-weather range and the mountains on the western side ofLynn canal. It is about 4 miles ( km.) broad at themouth, widens to about twice this breadth, and thenbranches. One arm, Muir inlet, extends due north about Excursion C Relief map of Glacier bay and Lynn canal. 15 miles (24 km.) to the ice cliffs of Muir glacier, whichsurround its head, and the other arm extends northwest-ward for 35 miles (56 km.) where it is terminated by theGrand Pacific glacier. The latter arm is branching, withsix good-sized tributary fiords also terminated by tidalglaciers. The extreme length of the bay from its mouthto the tidal front of Grand Pacific glacier is over 60 miles 124 (95 km.); the distance from the mouth to the head of Muirinlet is about 38 miles (60 km.). Except at the very mouth, the entire fiord and itsbranches are mountain-walled though there are small areasof low-lying land along portions of the shore line. At themouth of the bay, especially on the eastern side, there isan extensive flat extending eastward for several miles fromPt. Gustavus, and stretching northward to Beardslee islandsand the neighboring coast. This low area, including theislands and associated shoal
