Surveying the 120th Meridian and the Great Divide

SURVEYING THE 120TH MERIDIAN AND THE GREAT DIVIDE is the second book of a two-part series describing the initial Alberta/BC boundary survey undertaken between 1913-1924. SURVEYING THE 120TH MERIDIAN focuses on the years 1918-1924, when the Alberta crew continued the survey of the 120th meridian while the BC crew split off to continue mapping the Great (Continental) Divide. The Alberta/BC boundary survey was a unique Canadian project that combined talented surveyors, high-tech surveying equipment, rugged crew members and Canadian wilderness. This is a story of adventure and danger: the crew climbed mountains and surveyed from the peaks of the Canadian Rockies; slogged through the muskeg north of the Peace River; occasionally crossed rivers at high water; and often worked in the rain, snow or cold. The boundary survey produced the first detailed maps of the terrain along the divide and the first pictures of the northern Canadian Rockies taken from an airplane. But the most important legacy of this project is the collection of approximately 5,000 photographs developed from high-quality glass plate negatives. These photographs provide full panoramas of the Rocky Mountain landscape as it looked over a century ago. SURVEYING THE 120TH MERIDIAN AND THE GREAT DIVIDE combines the best of these photographs, diary entries and government documents to recount the astonishing journey of the surveyors and their crew members as they explored Canada's most dramatic landscape.
