According to John B. Branson, park ranger/historian with the National Park Service, Lake Clark Nat'l Park and Preserve, this collection may contain the earliest extant photographs of Tanalian Point, now known as Port Alsworth, and what is now Lake Clark National Park and Preserve. Two letters sent from Tanalian Point to A.S. Tulloch, from Otis M. "Doc" Dutton and Joe Kackley, provide some information about the region and the men. The collection contains several pictures of Walter Crane, Dean of the Penn. State School of Mines, who did assessment work on copper claims at Kasna Creek near Lake Clark. The collection also contains a photograph of Joe Kackley and Hannah Breece having a picnic on a Lake Iliamna island, which appeared in A Schoolteacher in Old Alaska, the Story of Hannah Breece, 1995.

John B. Branson (initials jb throughout the guide), added substantial information to the guide, including personal names and locations, with the aid of Iliamna-Lake Clark elders and others. This note is included with the individual items for which he gave us information in ArchivesSpace.
