What is Western Brook Pond?

Aerial View of the Pond
Waterfalls like this one are an important source of inflow into the lake. To get an idea of the size and height of the waterfall, look at the full-size trees in the lower right corner of the picture.
In some areas, smaller glacial flows joined the main arm of the glacier, resulting in hanging valleys like the one pictured here. Hanging valleys are U-shaped and have steep sides, just like the larger trough containing Western Brook Pond.
|Bedrock Geology and Erosion
The bedrock of the cliffs and the area surrounding the pond is part of the Grenville basement, which is made up of Precambrian gneiss with igneous intrusions of black diabase. Over time, sections of the cliffs have started to weaken and collapse, forming rubble cones, which are able to support trees better than the steep cliffs are. Where the walls are vertical, they are more stable and less likely to collapse.
Here are some more pictures of the cliffs surrounding the pond.
