A photograph mounted on a cabinet card showing a group seventeen on Umbrella Rock, atop Lookout Mountain, Tennessee.
Perched atop Point Lookout, Umbrella Rock is one of the most famous locations in the Chattanooga area. This unusual geological formation consists of several large stones topped by a large, flat slab. The rock has hosted innumerable visitors over the years, perhaps most famously Ulysses S. Grant. Formerly a popular location for photographs, erosion has made it unstable and it is now closed to the public.
