Cave and Basin National Historic Site of Canada

Cave and Basin National Historic Site of Canada is a hot spring located in Banff National Park. The site was developed for public use with a nearby swimming pool and bath-house and is now operated as a historic site open to the public. The official recognition refers to the cave, including its interior pool and the original vent hole, the basin, the hot-spring-fed waters and the vestiges of the building erected next to the vent hole between 1883 and 1885.

Cave and Basin was designated a national historic site of Canada because it is the birthplace of Canada's national parks.

The heritage value of Cave and Basin National Historic Site of Canada lies in the integrity and legibility of the cultural landscape that developed around the hot springs. The mineral spring issues from Sulphur Mountain where surface water penetrates the rock, absorbing minerals and being heated by geothermal energy to emerge in a cave and in a nearby basin before joining the bow river drainage system below. Long known to local Aboriginal people, the site was found by non-Aboriginal people in 1859 and reserved for public use with the surrounding 16 square kilometres in 1885. By 1887, development of this reserve had evolved into Canada's first national park, the Rocky Mountain Park of Canada.

Key elements contributing to the heritage value include:

- its interior pool, original surface vent hole, the basin (a pool of mineral water) in the open air adjacent to the Cave, the natural springs which flow into the Cave and Basin, and vestiges of the log shanty known as ''the Hotel'' built next to the vent hole between 1883 and 1885 in their extent, geophysical and construction materials;

- the health and wholeness of the natural features of the cultural landscape inside the Cave and immediately surrounding the Basin;

- the visual unity and functional inter-relationships between and among these natural features;

- a continuing flow of warm mineral water into the Cave and Basin from the natural springs;

- public accessibility to the site;

- the viewscapes from the site to the surrounding natural setting.
