I had the good fortune to make it to the Upper Cathedral Lakes Basin twice in one year! The views of Cathedral Peak and Amphitheater Mountain are stunning. When I visited in summer I noted the abundance of larch and so returned in fall to see the color explosion. Here are some images showcasing the changes between July 14th and October 2nd.
These last two images were both taken while on the October trip, the first on the way in and the second, from the same spot, on the way home!
