This first photo shows two valley glaciers, one entering the photo on the left side and the other entering the photo from the upper right corner. You can see the dark bedrock separating the two valley glaciers in the upper left portion of the photo. A small portion of the valley wall is also evident on the right side of the photo. This bedrock restricts the flow of ice across the landscape. The dark grey lines/ridges visible on the surface of the glaciers are moraines; they are not part of the bedrock valey walls.
