It is connected, via Johnstone Strait, Discovery Passage and associated channels, with the more or less enclosed waters of the Salish Sea (Figure 1). Anecdotal information from eBird lists suggests that this area supports a high diversity of marine birds in winter and during the periods of northward and southward migration (https://ebird.org/canada/ accessed 7 November 2020; hereafter “eBird”). In addition, this area is important for marine mammals, being used regularly by the Northern Resident Orca stock, and by Humpback and Minke Whales, Dall’s and Harbour Porpoises and Pacific White-sided Dolphins, and supporting several permanent haul-outs of Steller’s Sea Lions (Ford 2014).

  • Princess Louisa Inlet Wall, Journey to the Center of the Earth
    AAC Publications Princess Louisa Inlet Wall, Journey to the Center of the Earth Canada, British Columbia, Coast Mountains, Princess Louisa Inlet The Princess Louisa Inlet Wall, rising about 1,400 meters at the head of a fjord off Jervis Inlet. (1) PLI Trail (17 pitches, ED1/2 V 5.10+, Brodie-Rowat, 2002). (2) Journey to the Center of the Earth (25 pitches, VI 5.10+ C2, Besen-Heinrich, 2019). Neither party reached the summit, which may be unclimbed. Photo by Noah Besen Inspired by a story in the 2018 AAJ, which heralded unclimbed walls along the BC coast, I had been curing my winter blues with virtual flights through Google Earth. On the last day of 2018, I stumbled onto a low-res photo of a hulking mass of swamp and stone geotagged to Princess Louisa Inlet. Research revealed this wall to be 1,400m tall, with only one known route: PLI Trail (17 pitches, ED1/2 V 5.10+), established by John Brodie and Peter Rowat over the course of nearly two decades, and ending on a prominent pinncalce about halfway up the wall. Interest hastily morphed into a foolhardy obsession for me and Noah Besen, my partner for this project. Eight months later, in August 2019, we stood beneath that wall with our necks craning to see the granite dissolve into roiling cloud far above. With only a few Yosemite trade walls between us and not a single first ascent, we had gotten so caught up in scheming and dreaming that we neglected reality until we were starkly in it.

  • Marine Recreation in the Desolation Sound Region of British Columbia
    MARINE RECREATION IN THE DESOLATION SOUND REGION OF BRITISH COLUMBIA by William Harold Wolferstan B.Sc., University of British Columbia, 1964 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS in the Department of Geography @ WILLIAM HAROLD WOLFERSTAN 1971 SIMON FRASER UNIVERSITY December, 1971 Name : William Harold Wolf erstan Degree : Master of Arts Title of Thesis : Marine Recreation in the Desolation Sound Area of British Columbia Examining Committee : Chairman : Mar tin C . Kellman Frank F . Cunningham1 Senior Supervisor Robert Ahrens Director, Parks Planning Branch Department of Recreation and Conservation, British .Columbia ABSTRACT The increase of recreation boating along the British Columbia coast is straining the relationship between the boater and his environment. This thesis describes the nature of this increase, incorporating those qualities of the marine environment which either contribute to or detract from the recreational boating experience. A questionnaire was used to determine the interests and activities of boaters in the Desolation Sound region. From the responses, two major dichotomies became apparent: the relationship between the most frequented areas to those considered the most attractive and the desire for natural wilderness environments as opposed to artificial, service- facility ones. This thesis will also show that the most valued areas are those F- which are the least disturbed. Consequently, future planning must protect the natural environment. Any development, that fails to consider the long term interests of the boater and other resource users, should be curtailed in those areas of greatest recreation value. iii EASY WILDERNESS . Many of us wish we could do it, this 'retreat to nature'.

    ROCKFISH CONSERVATION AREAS Protecting British Columbia’s Rockfish Yelloweye rockfish Quillback rockfish Copper rockfish China rockfish Tiger rockfish (Sebastes ruberrimus) (Sebastes maliger) (Sebastes caurinus) (Sebastes nebulosus) (Sebastes nigrocinctus) Inshore rockfish identification Yelloweye rockfish (Sebastes ruberrimus) are pink to orangey red in colour with bright yellow eyes. Juvenile fish are a darker red with two white stripes along the sides. These stripes fade as the fish grows and large fish may have one or no white stripe along the lateral line. There are two prominent ridges on the top of the head. Fins may be fringed in black. Found in steep rocky reef and boulder habitats from 50 m to 550 m in depth but most common in 150 m (82 fa) depths. Maximum length up to 91 cm (36 in). Quillback rockfish (Sebastes maliger) are dark brownish black, mottled with orangey yellow. The lower anterior portion of the body is speckled brown. Dorsal fin spines are very high and moderately notched. The body is deep. Found in rocky habitats from the subtidal to 275 m in depth but most common between 50 m and 100 m (55 fa) in depth. Maximum length up to 61 cm (24 in). Copper rockfish (Sebastes caurinus) are brown to copper in colour with pink or yellow blotches. A white stripe runs along the lateral line on the anterior two thirds of the body. Two dark, sometimes yellow, bars radiate from the eye. Found in kelp beds and rock to gravel habitats from the subtidal to 180 m in depth but most common in water less than 40 m (22 fa).
