Walter Moberly, C.E., L.S.
b. 15 August 1832 — Steeple Aston, Oxfordshire, England
d. 14 May 1915 — Vancouver, B.C.
In 1865, he was appointed assistant surveyor general of the Colony of British Columbia. His job was to explore new routes for travel and trade for the growing population of the territory. It was during this time that he discovered Eagle Pass through the Gold Range between Shuswap Lake in the north Okanagan and the Columbia River at what is now Revelstoke. The story is that he shot at an eagle’s nest and watched the birds fly up a valley. Reasoning that the birds were unlikely to fly up a blocked valley, he followed them up and discovered the pass. In his recollections, he says he blazed a tree in the pass and inscribed the words, “This is the Pass of the Overland Railway.” The Canadian Pacific Railway did go through his pass but not for another 20 years.
After 1865, he left the province and worked in the mining fields of Utah.
In 1871, when British Columbia was about to enter Confederation with Canada, one of the terms was a promise by Canada to build a railway across the continent. Moberly was sought out by Sir Joseph William Trutch, British Columbia’s first provincial Lieutenant-Governor, and invited back to organize surveys for the railway. His survey crews headed out into the wilderness on the day the province joined confederation. Moberly’s survey crews were responsible for the territory around what is now Eagle Pass, Revelstoke, and Golden. From the time of his discovery of Eagle Pass, he formed the conviction that this was the best route for the railway. However, Sir Sandford Fleming, F.R.S.C., K.C.M.G., chief engineer of the railway project, asked Moberly to relocate his crews north to the Yellowhead Pass for the 1872 season. Moberly was very frustrated with these orders requiring him to abandon his preferred route.
After the 1873 survey season, Moberly left the Canadian Pacific Survey and moved to Manitoba. He continued to do private survey work there. Moberly retired in Vancouver after 1898 and died there in May 1915.
In 1871 Rylatt was recruited by fellow Royal Engineer veteran Walter Moberly [1832–1915], who was in charge of S party of the Canadian Pacific Railway Survey. Rylatt served as quartermaster for the party until 1873, when he got word that his wife had died. He wrote a memoir of the trip for his family, now published under the title Surveying the Canadian Pacific — Memoir of a Railroad Pioneer[1].
Upon starting, our party consisted of 4 officers (surveyors), 16 men, principally axeman about one half of them Canadian, 8 Mexican and Indian Packers, and one hunter for the party — a Bavarian. There were 45 animals in the Pack Train, each carrying about 300 pounds.
S Party spent winter 1871-72 on the Columbia River near the Blaeberry River at the west end of Howse Pass. Moberly, who had spent the winter in Ottawa, arrived at their camp on June 16th. The ‘S’ party spent the entire season moving their equipment, supplies and pack trains through the Athabasca Pass, and north, arriving in January at the east end of the Yellowhead Pass, which Rylatt consistently called the Leatherhead Pass. On May 13, 1873, Rylatt set off through the Yellowhead Pass with one companion and three horses, reaching Kamloops on June 14. Rylatt continued on by stage to his home at New Westminster.
And now, my reminiscence is done. I might go on to state I found an empty house, my goods intact but stored in a ware-house. My return to my empty home, and the replacing of everything therein as it used to be in the days that were gone. My sad thoughts as l lay stretched upon the bed my poor wife had breathed her last upon. My many visits to her grave, and my final sale of home and belongings, and my wandering away to seek another home, under another government. But to what end?
