This is the view from the lake, looking east toward Mount Thielson or Diamond Peak. It is easy to see how pointed the top of the mountain is in this picture. That is what gave it the ‘diamond’ designation. The picture actually makes the lake look larger than it really is, and it also makes Mount Thielson look farther away. Both are optical illusions. As the map shows, Mount Thielson is actually less than 5 miles from Diamond Lake.
How about this for a pretty lake? This view doesn’t show it, but the trees come right down to the short all the way around the lake.
