Dick Proenneke lived alone in the wilderness for 31 years in his 12 by 15 foot log cabin that he built with hand tools along the shore of Upper Twin Lake. He filmed the movie One Man's Alaska in the 1970s. This documentary helped establish four-million-acre Lake Clark National Park and Preserve in 1980. Dick was personal friend of Fred Hirschmann and it was an honor to take the HABS photos of his finely crafted cabin.

Listed on the National Register of Historic Places, the Brown & Hawkins store was established in 1904 and has been continuously operating in Seward, Alaska for 120 years. HABS photography and laser scanning was undertaken in 2022 to assist the Hawkins family with installing a fire protection sprinkling system across the historic building complex.

The original cabin in the Dutton-Kackley Complex on the shore of Lake Clark at Tanalian Point was likely built between 1909 to 1911. Doc Dutton and Joe Kackley, early Euroamerican prospectors in Alaska, lived on the site until their deaths in the 1940s.

With construction beginning in 1941 and completion in 1947, Anchorage's Fourth Avenue Theatre was one of the finest Art Deco theaters in the United States. Austin E. "Cap" Lathrop built the 1,000-seat theater when Anchorage had only 10,000 residents. Left in disrepair for many years, these HABS photographs by Fred Hirschmann are the last images taken of the cinema prior to demolition in the summer of 2022.

The George C. Thomas Memorial Library National Historic Landmark was built in 1909 in Fairbanks as the Episcopal Missionary Society's reading room providing "mental food" to Alaska's sourdoughs. In 1915 the library housed the first meeting between Tanana tribal chiefs and the United States government that began discussions on Alaska Native land claims that culminated 56 years later with passage of the Alaska Native Claims Settlement Act in 1971.

One of only three steam-powered wooden sternwheelers left in the United States, the SS Nenana, was placed in service in 1933 on the Tanana and Yukon Rivers and carried passengers and freight until 1954. Initially burning a cord of wood an hour, the Nenana stored 230 cords of firewood onboard. The ship is now permanently dry-docked at Pioneer Park in Fairbanks.

The Alaska Mission Operations Center (AMOC) building is home to the National Security Agency at JBER, Alaska. Adjacent is the Cold War era decommissioned Flare-9 circular Elephant Cage antenna array. Over two days in December of 2021, Fred Hirschmann did HABS documentation of the facility outdoors in temperatures of -4 to -12ºF so work could proceed with renovation of the AMOC building.
