  • Wildlife Information for Commercial Backcountry Recreation Opportunities in the North Central Monashee Mountains
    WILDLIFE INFORMATION FOR COMMERCIAL BACKCOUNTRY RECREATION OPPORTUNITIES IN THE NORTH CENTRAL MONASHEE MOUNTAINS 1.0 INTRODUCTION Amongst the wide variety of wildlife residing in the North Central Monashee Mountains are rare, threatened or endangered species as well as species of special management emphasis. Color code status has been assigned to species to indicate their vulnerability. Red listed: Includes any indigenous species or subspecies (taxa) considered to be Extirpated, Endangered, or Threatened in British Columbia. Blue listed: Includes any indigenous species or subspecies (taxa) considered to be Vulnerable in British Columbia. Special Management: Includes species which are not red or blue listed but are particularly sensitive to a variety of disturbances and require additional management emphasis. Backcountry recreation has the potential to impact wildlife and wildlife habitat, depending on the location, time of year, intensity, frequency and type of backcountry recreation activity. However, with thorough planning, impacts to wildlife from commercial backcountry recreation can be mitigated. 2.0 COMMERCIAL BACKCOUNTRY RECREATION GUIDELINES During 2000, the Ministry of Environment recognized the need for province-wide commercial backcountry recreation guidelines to address wildlife concerns and allow ministry staff to be provincially consistent in their evaluation of backcountry recreation proposals. The draft provincial guidelines are currently under review, and interim guidelines entitled Expanded Kootenay Region Interim Wildlife Guidelines for Commercial Backcountry Recreation in British Columbia (http://www.elp.gov.bc.ca/wld/comrec/crecintro.html) have been established. The guidelines will assist commercial backcountry operators and government agency staff in protecting wildlife and wildlife habitat while sustaining ecotourism and adventure travel in British Columbia.

  • UNIVERSITY of CALGARY Estimating Extreme Snow
    UNIVERSITY OF CALGARY Estimating Extreme Snow Avalanche Runout for the Columbia Mountains and Fernie Area of British Columbia, Canada by: Katherine S. Johnston A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE DEPARTMENT OF CIVIL ENGINEERING CALGARY, ALBERTA AUGUST, 2011 ©Katherine S. Johnston 2011 ABSTRACT Extreme snow avalanche runout is typically estimated using a combination of historical and vegetation records as well as statistical and dynamic models. The two classes of statistical models (α – β and runout ratio) are based on estimating runout distance past the β-point, which is generally defined as the point where the avalanche slope incline first decreases to 10°. The parameters for these models vary from mountain range to mountain range. In Canada, α – β and runout ratio parameters have been published for the Rocky and Purcell Mountains and for the British Columbia Coastal mountains. Despite active development, no suitable tall avalanche path model parameters have been published for the Columbia Mountains or for the Lizard Range area around Fernie, BC. Using a dataset of 70 avalanche paths, statistical model parameters have been derived for these regions. In addition, the correlation between extreme and average snowfall values and avalanche runout is explored. iii ACKNOWLEDGEMENTS Thank you to Bruce Jamieson for giving me the opportunity to work on this project, and for coordinating the financial support for this project. His thoughtful advice, numerous reviews, and inspirational leadership have helped make this a fantastic experience. My thanks to Alan Jones for providing numerous hours of guidance, mentoring, and thoughtful discussion throughout this project, and for facilitating data acquisition from outside sources.

Monashee Park Management Plan Approved by: October 1st, 2014 ____________________________ __________________ John Trewhitt Date A/Regional Director, Kootenay Okanagan BC Parks October 1st, 2014 ______________________________ __________________ Brian Bawtinheimer Date Executive Director, Parks Planning and Management Branch BC Parks Acknowledgements BC Parks is greatly indebted to visionaries such as Bob Ahrens, Ken and Una Dobson, Mike and Jean Freeman, Doug and Nesta Kermode, Paddy Mackie, Sid Draper, George Falconer, E.G. Oldham, R. Broadland, C.D. ‘Bill’ Osborne and early members of the North Okanagan Naturalists Club. In the 1950s and 60s much of the early groundwork for the establishment of the park was made by these individuals. Special acknowledgement is owed also to Ernest Laviolette, Eugene Foisy and Charlie Foisy. Their wilderness adventure over several months one summer in the 1960s was captured on the film “The Call of the Monashee”. This film, and the publicity it created, was another pivotal component towards the protection of this spectacular wilderness area for future generations. The Friends of Monashee Park and the Cherry Ridge Management Committee were instrumental in providing information on community interests and history within the park as were current members of the North Okanagan Naturalist Club, notably Kay Bartholomew and Pamela Jenkins. Dale Kermode provided invaluable historical photos of his late father’s (Doug Kermode) early explorations in the park.

  • Avalanche Characteristics of a Transitional Snow Climate—Columbia Mountains, British Columbia, Canada
    Cold Regions Science and Technology 37 (2003) 255–276 www.elsevier.com/locate/coldregions Avalanche characteristics of a transitional snow climate—Columbia Mountains, British Columbia, Canada Pascal Ha¨gelia,*, David M. McClungb a Atmospheric Science Program, University of British Columbia, 1984 West Mall, Vancouver, British Columbia, Canada V6T 1Z2 b Department of Geography, University of British Columbia, Vancouver, British Columbia, Canada Received 1 September 2002; accepted 2 July 2003 Abstract The focus of this study lies on the analysis of avalanche characteristics in the Columbia Mountains in relation to the local snow climate. First, the snow climate of the mountain range is examined using a recently developed snow climate classification scheme. Avalanche observations made by a large helicopter operator are used to examine the characteristics of natural avalanche activity. The results show that the Columbia Mountains have a transitional snow climate with a strong maritime influence. Depending on the maritime influence, the percentage of natural avalanche activity on persistent weak layers varies between 0% and 40%. Facet–crust combinations, which primarily form after rain-on-snow events in the early season, and surface hoar layers are the most important types of persistent weak layers. The avalanche activity characteristics on these two persistent weak layers are examined in detail. The study implies that, even though the ‘avalanche climate’ and ‘snow climate’ of an area are closely related, there should be a clear differentiation between these two terms, which are currently used synonymously. We suggest the use of the term ‘avalanche climate’ as a distinct adjunct to the description of the snow climate of an area.

  • Introducing Okanagan College 2010-11 Viewbook Introducing Okanagan College
    Introducing Okanagan College 2010-11 Viewbook www.okanagan.bc.ca introducing okanagan college Hi, my name is Arianne and I’m a second-year Business Administration student at Okanagan College. I’m here to walk you through our viewbook so you can get a student’s perspective of Okanagan College. Before we get going let me tell you a little about my school. Okanagan College is a community college that offers more than 120 degree, diploma and certificate programs in business, university studies, health and social development, engineering technologies, continuing studies and trades. This school has been around since 1963 and it has a long history of providing education in the Okanagan, Similkameen and Shuswap-Revelstoke regions. After I finished high school I decided to go to Okanagan College because I’d heard really good things about the College and wanted to stay close to home. I also watched my older brother complete his business degree at the College and I could really see myself as an Okanagan College student. I’m from Kelowna, but lots of students come from all over to go to Okanagan College. It is a school with a solid reputation, great professors and is a great place to make new friends and have some fun…but not too much fun. Anyways, let’s get started. Quick Facts Okanagan College: • Is the largest community college in BC east of the Lower Mainland with 1000 employees serving more than 19,000 students. • Serves the Shuswap-Revelstoke, North, Central, and South Okanagan-Similkameen regions with major campuses in Salmon Arm, Vernon, Kelowna and Penticton and education centres in Revelstoke, Summerland and Oliver.

  • Sol Mountain Touring: Backcountry Comfort in British Columbia’S Monashee Mountains by Debbie Mckeown
    Sol Mountain Touring: Backcountry Comfort in British Columbia’s Monashee Mountains By Debbie McKeown hen I first spot Sol Mountain Lodge, it looks like a small dot in a wilderness of Wuntouched white. The helicopter almost skims the top of the snow-laden trees as we make our final approach. It touches down, is quickly unloaded and takes off again, leaving me here for the next four days. Sol Mountain Touring’s backcountry lodge is located in Canada’s spectacular southern Monashee Mountains mid-way between Vernon and Revelstoke, British Columbia. I feel like I have been transported to another world. I am greeted by Aaron Cooperman, one of the friendly owners of Sol Mountain Touring and a certified ACMG mountain guide. Aaron’s first priority is getting the new guests on track with some basic safety training. We are outfitted with avalanche beacons and instructed on their use including a practice session of burying and searching for them. Sol Mountain Touring’s high safety standards require snowshoers, cross-country skiers and backcountry skiers to wear the beacons at all times when away from the lodge. 1 And then … the reason I came. I strap on my snowshoes and head out to explore with Aaron and several other guests. It is snowing hard for much of the day, adding fresh powder to the significant existing snowpack. While this makes for slow going, I feel privileged at the opportunity to enjoy such pristine wilderness. There are simply no other tracks, animal or human. When the sky clears slightly, the pale light of the sun magically shines through a snow squall.

  • The Cariboo and Monashee Ranges of British Columbia: an Alpinist’S Guide
    1 THE CARIBOO AND MONASHEE RANGES OF BRITISH COLUMBIA: AN ALPINIST’S GUIDE by EARLE R. WHIPPLE Even today, British Columbia is still a wilderness of mountains, valleys, glaciers, forest and plateau. The Columbia Mountains (Interior Ranges; which include the Cariboo and Monashee Ranges) lie within British Columbia, west of the Canadian Rockies and the southern Alberta-British Columbia border. This guide describes the access and mountaineering in these two ranges. Aside from parts of the Coast Range and the northern Rockies, the Cariboo and Monashee Ranges are the most isolated in B.C. However, if one listens to the helicopters from the lodges in these ranges, when camped there, one may question this. Large, active glaciers (now in retreat) with spectacular icefalls exist in the mountains of the western part of the Halvorson Group, the northern Wells Gray Group, the Premier Ranges, the Dominion Group and northern Scrip Range; there is climbing on rock, snow and ice, and routes for those climbers wishing easy, relaxing climbing in beautiful scenery. Good rock climbing on gneiss is in the southern Gold Range and Mt. Begbie in the north. There are also locales offering fine hiking on trails or alpine meadows (Halvorson Group, southern Wells Gray Group, southern Scrip Range, and the Shuswap Group), and backpacking traverses have been worked out through the Halvorson and Dominion Groups, the Scrip Range and the Gold Range. Beautiful lake districts exist in the northern Cariboos, and the Monashees. The area covered by this book starts northwest of the town of McBride, on Highway 16, southeast of Prince George, and extends south to near the border with the U.S.A., staying within the great bend of the Fraser River, and then west of Canoe Reach (lake; formerly Canoe River) and just west of the lower Columbia River south of its great bend.

  • Kettle River Watershed Analysis Midway, British Columbia to Stream Headwaters
    1 Kettle River watershed analysis Midway, British Columbia to stream headwaters Robert Maciak, Trevor Ford, Jenn Schroeder 2 Table of Contents Introduction p. 3 Watershed Description p. 4-10 Issues concerning quality p. 10-13 Issues concerning quantity p. 14-16 Recommendations p. 16 Monitoring strategies p. 18-20 Summary p. 21 References p. 21-22 3 Introduction The Kettle River flows from its headwaters in the Christian Valley, located in the Southern Interior of British Columbia, Canada to the Columbia River in Washington State, USA. We have chosen the drainage upstream of Midway, BC as our sample segment. This is an ideal location for analysis for several reasons: First, the headwaters are located in this area, as are two notable tributaries, the West Kettle River and Boundary Creek; second, the Kettle is a trans-boundary river shared by both Canadian and American riparians and Midway, British Columbia is where the river first crosses the border, making it an important point internationally; third, there are a variety of land use and water quality issues; and finally, Environment Canada has available data sets for the Kettle River at Midway from 1972 to present (BWP Consulting, 2003). Before crossing into the United States, the Kettle River’s resources affect both local riparians as well as visitors. The primary value of the river is irrigation for agricultural purposes. Although, water quality in the river is reported to be excellent, there are concerns of high fluoride levels and increasing levels of fecal coli form (BC Ministry of Environment, 1996). During the summer months the Kettle is used widely by locals and visitors alike for recreational purposes.
