They are eroded away by the wind just like the rocks in the Dry Valleys. Once, an Adelie penguin was found here. Our camp surroundings are unbelievable. Other than the sound of the wind tugging and whistling past my hood, Lake Bonney is refreshingly quiet. Tall, snow-covered mountains surround our camp.
Huge glaciers spill down the sides of the mountains.
They are called ventifacts, and their windward sides have been polished smooth. The Dry Valleys were formed when the terrain uplifted faster than the glaciers could cut their way through them. Eventually the glaciers were stopped by high necks at the head of each valley. There is ice on the lake, but the ice formations are very different. This is the ice that will melt later in the summer.
