Migration
Within this itinerary, the possibilities are endless and totally dependent on the adventurous minds of the guests and captain.
Upon departure your yacht will travel up the outer coast of Baranof and Chichigof Islands viewing the sea lions, sea otters and puffins of the St. Lazaria National Wildlife Refuge along the way. We will anchor in a secluded bay on the rock strewn outer cost of Chichigof Island.

The Whales of Glacier Bay Whales, symbolizing the struggle to preserve nature, include the largest creatures our world has known. Blue whales weighed up to 200 tons before whaling days. Sixty to 100 million years ago the ancestors of today's whales were land dwelling, warm-blooded, air breathing mammals who successfully returned to the seas to live. Alaskan waters boast 10 species of baleen whales and 5 toothed whales. Glacier Bay waters boast 2 of the baleen whales, the minke and humpback, and 1 toothed whale, the orca. The whales' appeal mixes familiarity and strangeness. Whales live in family groups, aid each other in distress, and talk to each other. Some serious observers credit whales with rational thought.
Orca whales feed on various marine animals, including fish, sea lions, seals, porpoises, sharks, squid, and other whales. Also called killer whales, orcas can hunt in teams and have killed blue whales, the world's largest animals. Male orca whales average about 23 feet long; the females less. They have no natural enemies. Thought to be highly intelligent, orcas are readily trained in captivity. They can swim at a steady 29 miles per hour. Their distinctive, largely triangular dorsal fin may reach nearly 6 feet high on old males. Humpback whales are the most acrobatic of whales, heaving their massive selves by leaps and turns out of the water. Humpbacks are both cosmopolitan -- found in all oceans -- and endangered. Only about seven percent of their pre-whaling numbers remain. Coastal feeders who love shorelines, bays, and fjords, they are naturals for Alaska, which boasts nearly 34,000 miles of tidal shoreline. Humpbacks feed here on krill, shrimp, and various fish, including capelin. Humpbacks feed heavily because, unlike most birds and mammals, they do not feed year round. Humpbacks must store enough fat in summer to last the rest of the year. Adults average 40 to 50 feet long, females being the larger. Adults weigh in at about three-quarters of a ton per running foot. An adult humpback has from 600 to 800 baleen Plates in its mouth. These plates end in bristles. In the feeding process, huge masses of sea organisms are scooped into the mouth. Then the water, some 150 gallons at a shot, is expelled while the plates filter in the edibles. Were you to stare into a humpback's mouth -- which opens to 90 degrees -- you might not readily discount the Biblical mishaps of Jonah. Glacier Bay humpbacks have been observed working singly or in pairs to cast a "net" of bubbles about their prey and then harvesting the hapless creatures -- probably shrimp and other slower-moving organisms -- caught in their airy illusion. To see these large whales in their native habitat surely counts as one of the great experiences of a lifetime. The situation of whales, and particularly of the endangered humpback whales, in Glacier Bay has recently been under intensive scrutiny by scientists. The purpose of the studies has been to learn enough about these awe-inspiring creatures to protect them. The numbers of whales present can vary dramatically from year to year. Whether these variations are wholly natural or not is uncertain. Historically, most of our information about whales derives from attempts to harvest them, not to save them from extinction. Enter Glacier Bay and you cruise along shorelines completely covered by ice just 200 years ago. Explorer Capt. George Vancouver found Icy Strait choked with ice in 1794, and Glacier Bay was a barely indented glacier. That glacier was more than 4,000 feet thick, up to 20 miles or more wide, and extended more than 100 miles to the St. Elias Range of mountains. But by 1879 naturalist John Muir found that the ice had retreated 48 miles up the bay. By 1916 the Grand Pacific Glacier headed Tarr Inlet 65 miles from Glacier Bay's mouth. Such rapid retreat is known nowhere else. Scientists have documented it, hoping to learn how glacial activity relates to climate changes. The park includes some 12 tidewater glaciers that calve into the bay. The show can be spectacular. As water undermines some ice fronts great blocks of ice up to 200 feet high break loose and crash into the water. In Johns Hopkins Inlet, several peaks rise from sea level to 6,520 feet within just 4 miles of shore. The great glaciers of the past carved these fjords, or drowned valleys, out of the mountains like great troughs. Landslides help widen the troughs as the glaciers remove the bedrock support on upper slopes. Tlingit Indians were the original inhabitants of Glacier Bay and still consider it their ancestral home. Hunters and gatherers of salmon, seals, berries and roots, they were driven from the bay by advancing glaciers during the Little Ice Age. Naturalist and adventurer John Muir is credited with discovering the bay in 1879, and tourism to this land of ice and snow began soon after. Pioneering homesteaders began farming in Gustavus around 1923, when fish canneries and salteries doned the region. Though a few hardy men and women have chosen to live in Glacier Bay and on the outer coast in times past, the area remains largely isolated and undeveloped. Guided
kayak and backpack trips can be arranged, as well as raft trips down the
Alsek River, and hunting and fishing guides and lodging in the Preserve.
