Yellowknife Bay, Mars created by the presence of liquid water, suggesting the presence of an ancient lake which could have sustained microbial life. The geologic depression takes its name from the city Yellowknife, capital of the Canadian Northwest Territories, in honor of the 4 billion year old rock in the region surrounding the city, which matches the approximate age of the uncovered rock in Gale Crater. Yellowknife Bay is a 5-meter geologic depression located in the large impact crater known as Gale Crater. The Crater is located on Mars near the northwestern part of the Aeolis quadrangle just south of the planet's equator.
Garden of the Provinces and Territories of Public Works and Government Services Canada, officially renamed the park. In December 2015, the federal government requested that the National Capital Commission approve the garden as the site of the proposed Memorial to the Victims of Communism rather than its previously approved site, a plot of land by the Supreme Court of Canada building. One quarter of the site is composed of formal terraces, with the flags of the provinces and territories in the order of their entry to Confederation. Bronze plaques include the floral emblems for each of the provinces and territories. A tall fountain symbolizes a tree.
