These principles reflected the member's goal to create a club that promoted the natural heritage of Canada while encouraging the urban classes of society to exercise in the outdoors. In 1923, the club was involved in activism concerning the construction of hydroelectric dams in places such as Waterton Lake, the Spray Lakes, and Lake Minnewanka. This put the ACC at the forefront of conservation groups, which helped it to create the National Parks of Canada in 1923. Beginning in 1906 and continuing until 1950, the Alpine Club of Canada progressed their relationship with the National Parks of Canada to promote outdoor activities, mountaineering and conservation. After the two World Wars, the ACC's philosophy progressed from being centered around strict conservation of the environment to encouraging outdoor recreation while maintaining a respectful appreciation of Canada's wilderness. The ACC and the NPC worked together to expand the parks system for easier access to the public. During these formative years, the ACC surveyed much for the Canadian Rockies which had been previously unmapped. The club also acted as management for the new National Parks board and aided with administration. The ACC aided in restoration of natural areas that were to be integrated into the parks while establishing the Park's conservation policies. As the National Parks in both the United States and Canada gained popularity, outdoor recreation became a prominent activity for many Canadians, which helped shape the ACC's goal and mission.
