Abraham Lake is an artificial lake on North Saskatchewan River in western Alberta, Canada. Abraham Lake has a surface area of 53.7 km2 and a length of 32 km. It was built on the upper course of the North Saskatchewan River, in the foothills of the Canadian Rockies. It lines David Thompson Highway between Saskatchewan River Crossing and Nordegg. Abraham Lake was created in 1972, with the construction of the Bighorn Dam. The Government of Alberta sponsored a contest to name the lake in February 1972, during the final stages of construction of the Bighorn dam. Students across the province were asked to submit names taking into consideration "historical significance, prominent persons, geography and topography, and the value of the lake." It was named for Silas Abraham, an inhabitant of the Saskatchewan River valley in the nineteenth century. Although man-made, the lake has the blue color of other glacial lakes in the Rocky Mountains, which is caused by rock flour as in other glacial lakes. The Cline River Heliport is located on the western shore of the lake.

Spotted Lake is a saline endorheic alkali lake located northwest of Osoyoos in British Columbia in Canada. It is located near the city of Osoyoos, beside Highway 3. Spotted Lake is very highly concentrated with numerous different minerals. It contains some of the highest quantities (in the world) of magnesium sulfate, calcium and sodium sulphates. It also contains extremely high concentrations of eight other minerals as well as some small doses of four others such as silver and titanium.
Most of the water in the lake evaporates over the summer, leaving behind all the minerals. Large “spots” on the lake appear and depending on the mineral composition at the time, the spots will be different colors. The spots are made mainly of magnesium sulfate, which crystallizes in the summer. In the summer only the minerals in the lake remain, and they harden to form natural “walkways” around and between the spots. Today there is a small sign nearby telling visitors about the lake’s healing powers. However a fence protects the lake-shore from liabilities of public access. Nevertheless the lake can be easily seen from nearby roads, and many do stop to admire.

Moraine Lake is a glacially-fed lake in Banff National Park, 14 kilometres outside the Village of Lake Louise, Alberta, Canada. It is situated in the Valley of the Ten Peaks, at an elevation of approximately 6,183 feet. The lake has a surface area of .5 square kilometres. The lake, being glacially fed, does not reach its crest until mid to late June. When it is full, it reflects a distinct shade of blue. The colour is due to the refraction of light off the rock flour deposited in the lake on a continual basis.
The area around the lake has several walking/hiking trails which are, from time to time, restricted. This is the one most commonly taken by tourists. The Rockpile Trail along the actual moraine is approximately 300 metres long, with an elevation change of 24 metres. The view of the lake from the top of the rockpile is one of the most photographed locations in all of Canada. That view of the mountains behind the lake in Valley of the Ten Peaks is known as the Twenty Dollar View, as Moraine Lake was featured on the reverse side of the 1969 and 1979 issues of the Canadian twenty dollar bill. Along the same trailhead, the Consolation Lakes trail starts, which is approximately 3 kilometres long, with an elevation change of 90 metres. Upon reaching Consolation Lakes hikers may continue along to the upper lake, which is not visible from the end of the lower lake. There is, however, no clearly marked trail, and can often be a scramble over large rocky areas.
Near the canoe docks of Moraine Lake Lodge there is another trailhead. This trailhead is the start of two trails, one of which branches out into four different trails - so there are in total, five trails starting at that trailhead (Moraine Lake Lakeshore Trail, Eiffel Lake, Wenkchemna Pass, Larch Valley, and Sentinel Pass). The Lake Louise & Yoho Map provides information on these trails.

The Biosphère is a museum in Montreal dedicated to the environment. It is located at Parc Jean-Drapeau, on Île Sainte-Hélène in the former pavilion of the United States for the 1967 World Fair Expo 67. The architect of the geodesic dome was Buckminster Fuller. The building originally formed an enclosed structure of steel and acrylic cells, 76 metres in diameter and 62 metres high. The dome is a Class 1, Frequency 16 Icosahedron. A complex system of shades was used to control its internal temperature.
Architects from Golden Metak Productions designed the interior exhibition space. Visitors had access to four themed platforms divided into seven levels. The building included a 37-metre-long escalator, the longest ever built at the time. The Minirail monorail ran through the pavilion. In August, 1990, Environment Canada purchased the site for $17.5 million to turn it into an interactive museum showcasing and exploring the water ecosystems of the Great Lakes-Saint Lawrence River regions. The museum was inaugurated in 1995 as a water museum, and is a set of enclosed buildings designed by Éric Gauthier, inside the original steel skeleton. The Biosphère changed its name in 2007 to become an environment museum. It offers interactive activities and presents exhibitions about the major environmental issues related to water, climate change, air, ecotechnologies and sustainable development.
