Description This is a view of Crater Lake with a portion of Wizard Island visible on the left side. The picture is taken from the wall at the beginning of the westward loop up from the visitor center at Crater lake. If you look closely you might find a squirrel on the bottom right. The volcanic crater is filled with deep blue water. This is the deepest lake in North America. You can see Wizard Island on the left hand side, quite small when seen from the road but actually several hundred feet tall in the middle of the lake.
