It is suggested that consideration should be given to the possible construction of a rail line from Prince George northward down the Parsnip Valley to serve the extensive forest stands in this area and its extension through the Pine Pass to the Pine River coalfield—a southerly extension of the Carbon River field—where immense reserves of coal of superior quality are known to exist. Some detailed reference to this coalfield is made in the chapter dealing with Physiography and Geology. Air TRANSPORTATION Air transport has brought rapid changes to the Canadian Northwest during the past few years. Whereas the region was once remote and inaccessible except by slow water transport, within the last decade airfields have been con structed in numerous locations, and during the war the region was on the busy Great Circle air route to Alaska and Eastern Asia. These changes in accessibility and all- season contact have greatly aided the recent exploration and development of the region, and will play an important part in all future plans. EARLY HISTORY Aviation made its daring beginnings in the Canadian Northwest in the early 1920's. Following pioneer flights in Alaska in 1920, two planes first entered Mackenzie District on skis in March, 1921. They reached Fort Simpson before being stopped by accidents and engine trouble, and in the following June one of the planes flew to Fort Norman, landing on floats. Other historic flights were made in northern British Columbia in 1922 and planes reached the Yukon in 1927. In the next few years the Northwest was brought to the attention of air-minded persons when long distance round-the-world flyers passed over this region in 1928, 1930, and 1931. To the average person, however, the significance of the routes of these flights remained unnoticed. Air companies were entering Mackenzie District about this same time and brought a newer and faster method of northern prospecting to the mining industry. In the following decade daring of the Canadian bush-pilots became famous, and they built up a wealth of experience which was invaluable in war-time development of the region. Air trafic developed rapidly throughout the Northwest, serving trappers, traders, miners, and prospectors. Supplies were taken into the north country and valuable cargoes of ore concentrates and furs were brought out. As the “bush- pilots” gained wider knowledge and experience, they were prepared to accept assignments in both winter and summer. Since the numerous lakes and rivers afforded good landing facilities, air transport adapted itself to these features and operated with small aircraft equipped with pontoons in summer and skis in winter. Apart from fuel supplies and buoys, bases were not expensive to locate or maintain. There were periods of inactivity, however, aggregating as much as three months of each year, when the ice on the lakes and rivers was breaking up in the spring and when it was forming in the autumn. During these times neither pontoons nor skis could be used, and all transport was at a standstill. NORTHWEST STAGING ROUTE In order to bring the Northwest into closer adminis- trative contact with the rest of Canada it became apparent that year-round landing facilities for wheel-equipped air- craft would have to be provided. Such bases would aid development by enabling larger planes to carry large loads at any time of the year. In 1939 the Government authorized the construction of an airway from Edmonton, Alberta, to Whitehorse, Yukon. Plans provided for airdromes at Grande Prairie, Fort St. John, Fort Nelson, Watson Lake, and Whitehorse with landing strips 3,000 feet by 500 feet, all capable of extension. Emergency landing fields were to be provided half-way between each of the above aero- dromes and half-way between Edmonton and Grande Prairie. This project would result in a series of landing fields at approximately 100-mile intervals over the whole route from Edmonton to Whitehorse, in accordance with standard airway practice. Construction of the airway proceeded rapidly and it was opened for through traffic in September, 1941. When war with Japan was declared in December, 1941, there was an airway available, remote from the Pacific Coast and free from danger of enemy attack, with modern aids to air navigation. It connected with the airways of Canada and the United States at Edmonton and Vancouver and led into the heart of Alaska. In time, war requirements made essential the enlarge- ment and expansion of the airway then available. The main airports were enlarged, air navigation facilities aug- mented, and living accommodation was provided for oper- ating personnel. Hangars and workshops for the mainten- ance of the aircraft, refuelling systems, urport lighting, increased power, and water supply were all added to the original airfields. This work was carried out in 1942 and 1943. In July, 1943, the Canadian Government closed out its contracts and withdrew its construction forces, having completed its program of construction at the main airfields. The United States Government then undertook for one year a further program of extension and pavement to meet the increasing volume of its air traffic. The next year the Canadian Government re-assumed responsibility for sions and other improvements. In addition to the aerodromes and secondary airfields that were constructed, a service road, the Alaska Highway, connecting the various airfields, was also built from Dawson Creek, B.C., to Fairbanks, Alaska. The airfields were provided with a telephone line along this road and were also connected with the Skagway to Whitehorse gasoline distribution pipeline which fed to Watson Lake and_ Fairbanks. exten- [127 }
