The Canyon was formed by the Lower Grindelwald Glacier. This Glacier does not exist any more, but the Lütschine flows through the floor of the canyon. During the winter months the water flow is much lower. Once spring hits, the river is flowing wildly from the melting snow.
The walls of the canyon are approximately 300 meters high. Julie and I both were amazed at the differences in temperature and wind levels. One section, you could barely feel the wind, but 100 meters up the trail it felt like a mini tornado.
