1871 During the 1871 Hayden Expedition, Yellowstone Lake was explored on July 29.

"On the morning of the 29th, Messrs. Stevenson and Elliott started across the lake in the Anna, the first boat ever launched on the Yellowstone, and explored the nearest island, which we named after the principal, assistant of the expedition, who was undoubtedly the first white man that ever placed foot upon it. Our little bark, which is well shown in figure 32,  whose keel was the first to plow the waters of the most beautiful lake on our continent, and which must now become historical, was named by Mr. Stevenson in compliment to Miss Anna L. Dawes, the amiable daughter of Hon. H. L. Dawes. My whole party were glad to manifest, by this slight tribute, their gratitude to the distinguished statesman, whose generous sympathy and aid had contributed so much toward securing the appropriation which enabled them to explore this marvelous region."
