These films were made by prospector and miner Harry Leonard primarily during the 1930s and 1940s at Fairbanks, Alaska, and at or near Wiseman, Alaska, a small mining community along the Middle Fork of the Koyukuk River in the Brooks Range about 270 miles north of Fairbanks. In 2019, the original films were preserved through funding from the National Film Preservation Foundation (NFPF); Reflex Technologies of Burbank, California, scanned the reels of original 8mm film and created digital DPX files, which were then output to new 16mm internegative and answer print film stocks by Video & Film Solutions of Rockville, Maryland. The original films, new internegative and answer print films, and digital files are all being preserved by the Alaska Film Archives at University of Alaska Fairbanks. Many of the following identifications are from film donor George Lounsbury.

Part 1 (AAF-1865) scenes include a fire in a Fairbanks building, Harry Leonard’s wife Savannah Leonard standing near car, Harry Leonard approaching the camera, cabins and sled dogs, Savannah Leonard with a broom and with snowshoes at the Leonard home on Dunkel Street in Fairbanks, and Harry Leonard waving. A pilot starts a Stearman bi-plane airplane on skis, followed by aerial views of Wiseman and mountains. Images back at Fairbanks include fire at the Hotel Alaska. Koyukuk region images include a small dam, large pump and pipe, and Harry Leonard with hydraulic giant moving material at Archibald Gulch on Nolan Creek.

Part 2 (AAF-1866) scenes include a dog team on the Chena River at Fairbanks, Soviet aviator Mavriky Slepnyov walking to camera with unidentified men, with Savannah Leonard, and with Harry Avakoff (in dark suit). Harry and Savannah Leonard and other men pose with airplanes at Weeks Field in Fairbanks, and then an airplane on skis takes off. In the Koyukuk region of Alaska, men at the Wiseman Roadhouse include (left to right) unidentified, Phil Sundquist, Ace Wilcox, Poss Postlethwaite, Albert Ness, Martin Slisco and unidentified. On the final pan of the men, Harry Leonard is the last man on the right. Next are images of Wild Lake, Phil Sundquist with rifle, and the Hope Family at camp, including Ludi Hope and her adopted son Henry, who was the son of Japanese whaler and miner James Minano. Following scenes of a lake are men including Ace Wilcox and Vern Watts at sluice box, Biner Wind’s mining camp, Biner Wind on the runners of a dog sled, Harry Leonard with dog in front of tent, Phil Sundquist sharpening a saw, spring breakup on the Koyukuk River, miners shoveling ore into sluice boxes at Biner Wind's mining operation on the Hammond River, Ike English by sluice box, and people gathered around an airplane at Wiseman. Next are scenes of Roshier H. Creecy panning a sample in a washtub over a campfire and standing by a cabin during the winter at Gold Creek. Roshier Creecy, born just after the Civil War ended, was one of the few known African Americans who made their living by prospecting and mining in Alaska in the early 1900s. Following this are scenes of Roshier Creecy pulling a sled over ice and then dogs pulling a sled on snow, Harry Leonard waving to camera, Roshier Creecy waving to camera, Wiseman as viewed from the hillside, a dog yard, a log church (possibly at Allakaket?), and aerial views during a winter flight in a biplane. Images at Fairbanks include the Chena River breaking up downtown, and airplanes at Weeks Field. After scenes of people posing for the camera, are images from the Wiseman area including Tishu Ulen and Joe Ulen and their family, self-tripping dam on Gold Creek, a snared black bear, moose, and Harry Leonard prospecting with pack dog. Next is a scene of people posing by an airplane on floats flown by Wiley Post with Will Rogers while it is parked on the Chena River at Fairbanks. This is followed by scenes of a grouse, mountains near Wiseman, hunters with caribou antlers and meat, and Harry Leonard with a sled hauling firewood in winter.

Part 3 (AAF-1867) images from the Wiseman area include high water running over Harry Leonard's Gold Creek dam, mining camp with small sluice boxes and prospect boiler, man shoveling ore into sluice boxes, and Harry Leonard at hunting camp with three moose heads. Images at Fairbanks include people at Weeks Field getting into single engine Wien Alaska Airlines airplane piloted by Herman Lerdahl, Richard Wien as a boy running toward the camera, and a Mirow airplane on skis. Images outside of Alaska include a United Airlines Mainliner and travel to cities at several locations. Scenes of travel across the United States from Key West, Florida, to New York City and El Paso, Texas, were possibly filmed by a friend of Leonard’s borrowing his camera.
