May and June in order to protect unweaned harbor seal pups. Johns Hopkins Glacier The Johns Hopkins Glacier rises from the Fairweather Range on the east slopes of Lituya Mountain and Mount Salisbury and has an easterly flow towards the head of Johns Hopkins Inlet, 1 mile (1.6 km) southwest of the terminus of Clark Glacier and 79 miles (127 km) northwest of Hoonah. Its rock, ice and snow depict a variety of impressive colors such as grey, blue and white. It was named in 1893 by H.F. Reid after the Johns Hopkins University in Baltimore, Maryland, which sponsored an expedition to this glacier. It is the only advancing tidewater glacier now (its advance started in 1924 when Grand Pacific Glacier started receding towards Tarr Inlet) and is combined with Gilman Glacier (first got attached to Hopkins in the 1990s, broke off and rejoined several times and once again it appears joined since 2000); both are advancing as one single ice block, and at the waterfront, has a width of with a depth of , rises to a height of and stretches to about upstream. Submarine calving has also been recorded. The Johns Hopkins Glacier, for example, cannot be approached any nearer than about by sea because of the volume of the ice blocks that break loose from its cliffs. Most visitors to the park come by cruise ship and thus view the glaciers from the water. Gilman Glacier Gilman Glacier got attached to Johns Hopkins Glacier sometime in 1990. In the following decade, the two glaciers merged and de-merged several times. However, in 2000 it was again attached to Johns Hopkins glacier and the two together are stated to be advancing along the steep ice face. Tarr Inlet The Tarr Inlet at the head of the Glacier Bay is a scene of ice and snow, and "sits cater-corner to Johns Hopkins Inlet". This inlet provides excellent views of the Grand Pacific Glacier to its north and the Margerie Glacier to its west. The west shore line of this inlet is steep and rocky, extends to up to a small stream where a beach has been formed. A further along the channel, a glacier knob is seen in the center of the west shore of the inlet. A cove formation here provides for good camping grounds, where strong winds and ice flows are experienced. This location also provides a panoramic
