Northern Passages & Glacier Bay Small ship exploration of Alaska’s northern passages and Glacier Bay Juneau to Sitka (or reverse) 7 Nights Dates: April – September 2019, 2020 Departs weekly on Saturdays Cost from: $2,995 Vessels : Wilderness Discoverer, Wilderness Explorer, Wilderness Adventurer Day-By-Day Itinerary: Juneau to Sitka DAY 1 Juneau, Alaska – Embarkation There’s nothing like a hearty greeting from your crew and some bon voyage bubbly. With all souls settled in on board, you’re underway. From the bow, Southeast Alaska welcomes you with Coast Mountain views. DAY 2 Captain’s Choice Lynn Canal or Chatham Strait, your captain makes the call. Either choice, go with the flow. The water is fine. The guides help you gear up, and lead your adventure along the rocky outcroppings. By kayak or paddle board, take in the size of this wilderness. Bald eagles dot the tree tops. Harbor seals bob up and under. Pods of orcas—the largest in the dolphin family— skim along the water’s surface. DAY 3 Glacier Bay National Park What a privilege. At 3.3 million acres—this UNESCO World Heritage Site and Biosphere Reserve is massive. At Bartlett Cove, a park ranger joins in on your day’s exploration and shares the park’s history. Orange-beaked puffins, guillemots, marbled murrelets are just a few possible sightings. Keep a tally—the list will grow. Arriving at South Marble Island, you can hear and smell ‘em before you see ‘em—it’s a haulout for sea lions. Perched above around the bend, watch for mountain goats, and lower along shore, foraging bears. Up bay, glacial silt turns the water a milky white. Margerie and Grand Pacific Glaciers—one holding steady, the other retreating. Lounging harbor seals laze on bits of bergs. And if time allows, tuck up in Tidal Inlet. End this very full day with your feet up for the sail into Icy Strait. DAY 4 Icy Strait Nearly to the Pacific Ocean, Icy Strait is remote and wild. The plan? Whales and marine mammals. Spouts and fin slaps are certain giveaways. More rollicking sea lions and birds. But don’t forget to look straight down. Porpoises and dolphins may hitch a ride on the bow wave. And don’t worry about missing any wildlife; it’s a favorite mission of the crew to point out any creatures they spot. Make a break for it and head for a quiet pocket along the rugged coastline. A different sort of wild than the open strait, muskeg leads to forest bushwhacks. Skiff the shore and down along kelp- threaded channels. DAY 5 Chichagof Island / Peril Strait Kick off the morn with on-deck yoga stretches (your guides love it when you join them). Meander through glacier-carved fjords along the Chichagof coast. Then stop. It’s a prime time to lower the kayaks and skiffs. Camera in hand, set off on land and sea explorations. Closer inspection by skiff, moss-dripping trees run right down to the water. Any bears in there? With one of the world’s largest populations of bears, it’s possible. Go searching for giant trees and tidal pools. Hiking in the Tongass, it won’t take long to find them. Your eagle-eyed guides lead the pack—and pull up the rear. Later, wend along a twisting channel known for dramatic currents. Peril Strait runs 50 miles to Salisbury Sound. DAY 6 Sergius Narrows / Neva Strait There’s an eerie, enigmatic feeling in these woods. Morning fog catches like cotton balls on trees. The aptly named narrows squeezes to only 300 feet wide in one spot and a shallow 24 feet deep. The shorelines are close and it’s good territory for play. Skiff ashore and hike into the backcountry. Otters back float working to crack snacks resting on their bellies. Opening at Hoonah Sound, the squeeze is back on. Wind into Neva Strait. Watch the scenery change in the late fading light—from the hot tub of course. DAY 7 Krestof & Nakwasina Sounds There aren’t many straight lines along Baranof Island. Its western side is spattered with remote, uninhabited islands. These features mean endless opportunities for adventure. Secluded coves. Tree-covered islets. Drop anchor, pick your modus operandi, and get going. Kayak, paddle board, or skiff—you’re on the level with curious sea lions and possibly whales. Rocky intertidal zones make good beach combing. Turn a stone or two to see what’s underneath. There are no groomed trails here—get out on a guided hike John Muir would approve of. Toast your voyage with a festive Farewell Dinner and a “photo journal” of your trip. A gift to you, from your expedition team. DAY 8 Sitka, Alaska – Disembarkation Cruise into Sitka this morning over breakfast. Farewell new friends! Disembark and transfer to the airport or your hotel stay or land tour.

PO Box 16304 Seattle, WA 98116-0304 Ph: 206-932-8352 PORTS AND PLACES The places you visit play a starring role throughout every journey. While this list isn’t exhaustive of every nook-and-cranny you’ll explore along the way, we’ve included descriptions of key ports and places to help you get to know the wilderness areas, landmark locations, notable regions, and coastal towns relevant to this itinerary Chichagof Island Chichagof Island is the 5th largest island in the United States and one of the ABC islands of Alaska. It sits at the northern end of the Alexander Archipelago. Separated from Baranof Island by the Peril Strait to the north, Chichagof Island has the largest population of bears per square mile of any place on earth and is protected by the West Chichagof-Yakobi Wilderness area. Glacier Bay National Park & Preserve Glacier Bay Park and Preserve is reportedly the most sought after park to visit in the United States and it is no wonder. Where else will you find a 25 mile-long river of ice still carving the land just as it has for the past several thousand years? When Captain Cook and George Vancouver sailed by in 1879, they saw a 20-mile wide glacier where today the entrance of the park lies, as well the wilderness lodge and park headquarters. Over the past 200 years, this wall of ice has retreated an astonishing 65 miles north, splintering into a vast number of tributaries spaced throughout the entire park. Each glacier has its own name and character; our captain will decide which to visit for the day depending on ice conditions and wildlife sightings. Visiting Glacier Bay Park is also like visiting a wildlife park. Here bears, goats, moose, whales, sea otters, and all the creatures of the water and forest flourish, completely protected from man. A National Park Ranger joins us for our entire journey to explain the park's geology, glaciology, wildlife, and its deep roots in Tlingit culture. Juneau, Alaska Surrounded by the rich, green Tongass National Forest, and located on beautiful Gastineau Channel, Juneau is an important port and a popular tourist destination. Unique because it is the only state capital in the United States that is inaccessible by road, Juneau sits at sea level below the steep mountains that are home to the Juneau Icefield and the Mendenhall Glacier. Its temperate climate produces remarkable scenery with miles of hiking trails through woods and alpine meadows providing a glimpse of just how rugged the rainforest of Southeast Alaska is. The Auke tribe of Tlingit Indians were the first settlers in the Juneau area. They lived there peacefully enjoying the abundance of food and natural resources until the gold rush began. First named Rockwell and then Harrisburg, Juneau was finally named after gold prospector Joseph Juneau. In 1880, he and his partner, Richard Harris, discovered gold nearby, and the city quickly developed into a gold rush town. During the lucrative 60 years of gold mining in the area Juneau was home to three of the world's largest gold mines: The Alaska Juneau mine, the Alaska Gastineau mine, and the Treadwell mine. These three mines produced $158 million worth of gold making Juneau one of the world's major gold mining areas until the 1940s when costs outstripped the value of the gold. However, since 2005 the gold mining industry has been experiencing a resurgence. Officially designated the capital of the Territory of Alaska in 1900, it did not function as the capital until the government offices were moved there from Sitka in 1906. In 1959 Juneau became the official state capital when Alaska was admitted to the United States. Today, its approximately 31,000 citizens live within a 3,255 square mile boundary, an amount of land that makes Juneau's city limits the largest state capital in the United States (and the only state capital that borders a foreign city.) Along with its delightful small town ambiance, Juneau has a number of art galleries, boutiques, historical sites, and museums. In town you can visit the Alaska State Museum, the House of Wickersham, the Patsy Ann Statue, the 5-stories-tall totem pole outside the Capital Building, the Juneau- Douglas City Museum, the Alaska-Juneau gold mine or the salmon hatchery. One of the most popular attractions in the area is Mendenhall Glacier, located only 13 miles outside the city.

In 1925, also, at the request of one of the companies engaged in packing salmon in the Port Moller district, along the northern shore of the Alaska Penin­ sula, the work done there in 1922 was repeated. The results of these experiments form the basis for the following report.

    Brown Bear (Ursus Arctos) John Schoen and Scott Gende Images by John Schoen

    Brown Bear (Ursus arctos) John Schoen and Scott Gende images by John Schoen Two hundred years ago, brown (also known as grizzly) bears were abundant and widely distributed across western North America from the Mississippi River to the Pacific and from northern Mexico to the Arctic (Trevino and Jonkel 1986). Following settlement of the west, brown bear populations south of Canada declined significantly and now occupy only a fraction of their original range, where the brown bear has been listed as threatened since 1975 (Servheen 1989, 1990). Today, Alaska remains the last stronghold in North America for this adaptable, large omnivore (Miller and Schoen 1999) (Fig 1). Brown bears are indigenous to Southeastern Alaska (Southeast), and on the northern islands they occur in some of the highest-density FIG 1. Brown bears occur throughout much of southern populations on earth (Schoen and Beier 1990, Miller et coastal Alaska where they are closely associated with salmon spawning streams. Although brown bears and grizzly bears al. 1997). are the same species, northern and interior populations are The brown bear in Southeast is highly valued by commonly called grizzlies while southern coastal populations big game hunters, bear viewers, and general wildlife are referred to as brown bears. Because of the availability of abundant, high-quality food (e.g. salmon), brown bears enthusiasts.

    East Baranof Island

    East Baranof Province as the highest peaks on Admiralty Island, but they intercept more moisture and are more heavily glaciated. They also appear more jagged, because regional ice levels were somewhat lower during the Great Ice Age, and therefore a greater proportion of their summits stood free of the rounding effects of ice. The unnamed 5,328-ft (1,625 m) mountain at the head of Baranof River is the tallest peak on any Southeast island, and overlooks an icefield of about 5 mi2 (12 km2), the largest such expanse on the archipelago. Catherine Island is a giant “tombolo;” only during extreme high tides is it actually separated from Baranof Island by salt water. The largest streams and rivers draining the interior glaciated highlands are braided and aggrading where they reach the lowlands. Most deliver their silt burden into lakes before reaching the ocean. Only Glacial River, terminating in the south arm of Kelp Bay, carries glacial silt all the way into estuarine salt marshes, and is unique among all archipelago streams in this regard. The Clear River also enters these marshes, forming an instructive contrast. East Baranof Province is one of the wettest regions of Southeast.

In 1927 a number of ex­ periments were conducted in southeastern Alaska and one in Uganik Bay, Kodiak Island. In 1928 an experiment was carried out at Nicholaski Spit on the Alaska Peninsula. The experiments in southeastern Alaska were designed to fill in some of the gaps in the information that had been secured from previous experiments in thig district. The other experiments were designed to settle specific questions that had arisen in connection with the administration of the fisheries. .\lthough many details of the salmon migrations yet remain to be discovered, it is our opinion that the general features are now well enough known so that there is little need to continue general tagging experiments of the nature of those performed in southeastern Alaska in 1924 to 1927. It is planned, therefore, to use the method of tagging in the future only in connection with specific problems, such as those at Uganik Bay and Nicholaski Spit, which are covered by this report.

Schaefer1,3*, Beth Shapiro2,3 and Richard E. Green1,3 Abstract Background: Inferring the ancestry of each region of admixed individuals’ genomesisusefulinstudiesranging from disease gene mapping to speciation genetics. Current methods require high-coverage genotype data and phased reference panels, and are therefore inappropriate for many data sets. We present a software application, AD-LIBS, that uses a hidden Markov model to infer ancestry across hybrid genomes without requiring variant calling or phasing. This approach is useful for non-model organisms and in cases of low-coverage data, such as ancient DNA. Results: We demonstrate the utility of AD-LIBS with synthetic data. We then use AD-LIBS to infer ancestry in two published data sets: European human genomes with Neanderthal ancestry and brown bear genomes with polar bear ancestry. AD-LIBS correctly infers 87–91% of ancestry in simulations and produces ancestry maps that agree with published results and global ancestry estimates in humans. In brown bears, we find more polar bear ancestry than has been published previously, using both AD-LIBS and an existing software application for local ancestry inference, HAPMIX.
  • North America Summary, 1968

    North America Summary, 1968

    240 CLIMBS A~D REGIONAL ?\OTES North America Summary, 1968. Climbing activity in both Alaska and Canada subsided mar­ kedly from the peak in 1967 when both regions were celebrating their centen­ nials. The lessened activity seems also to have spread to other sections too for new routes and first ascents were considerably fewer. In Alaska probably the outstanding climb from the standpoint of difficulty was the fourth ascent of Mount Foraker, where a four-man party (Warren Bleser, Alex Birtulis, Hans Baer, Peter Williams) opened a new route up the central rib of the South face. Late in June this party flew in from Talkeetna to the Lacuna glacier. By 11 July they had established their Base Camp at the foot of the South face and started up the rib. This involved 10,000 ft of ice and rotten rock at an angle of 65°. In the next two weeks three camps were estab­ lished, the highest at 13,000 ft. Here, it was decided to make an all-out push for the summit. On 24 July two of the climbers started ahead to prepare a route. In twenty-eight hours of steady going they finally reached a suitable spot for a bivouac. The other two men who started long after them reached the same place in ten hours of steady going utilising the steps, fixed ropes and pitons left by the first party. After a night in the bivouac, the two groups then contin­ ued together and reached the summit, 17,300 ft, on 25 July. They were forced to bivouac another night on the return before reaching their high camp.
