Want to see what a tombolo looks like, or perhaps a pingo? These two geologic formations (the first a land-linking sandbar, the second a rock mound pushed up by permafrost) are among many examples illustrated at a site called Canadian Landscapes. The 700-some photographs—taken by scientists with the Geological Survey of Canada over the last 30 years—can be viewed by geologic type, province, or by clicking an interactive map. In this picture from the northern territory of Nunavut, a 30-meter-high dike (and a smaller one across the waterfall) formed when magma was injected into bedrock that subsequently eroded away. The site will continue to expand its geographic coverage to “illustrate the great diversity of Canadian scenery.”
