Here's a shot from "Billy the Kid in Texas" (1940), an early entry in Producers Releasing Corp.'s Billy the Kid series starring Bob Steele. (He was later replaced by Buster Crabbe, who went on to do most of PRC's Billy the Kid movies.) This is one of the best shots I've seen of the Gorge Cabin, and as a bonus it shows The Wall in the background, along the top of the photo. Potato Rock, which sat atop The Wall, can be seen directly above the point where the wooden and stone sections of the cabin join, at the very top of the photo. The Wall was eventually destroyed to make way for condo development, and some of those condos now occupy the space where the cabin once stood.
The cabin was built mainly of stone — or material that was made to look like stone. (You can't ever be sure with these old movie buildings — the actual construction was typically plaster.) The smaller wooden section on the left was added later. The cabin was located in the Upper Gorge section of the Lower Iverson, in an area that is now filled with condos. It appears mainly (or exclusively) in productions filmed from 1938-1944. According to some researchers, after that period the building was moved to the Upper Iverson — to an area known as Hidden Valley. I believe from that time on it appears in the setting seen here. I've never proved to my satisfaction that it's the same cabin, but it does look similar. This much is certain: The Gorge Cabin disappeared from the Gorge by mid-1944, and later that year an adobe village appeared in the same general location. The adobe village is seen in The Desert Hawk later in 1944, and in other productions of the late 1940s and possibly into the 1950s.
The Gorge Cabin may have appeared as early as 1937, but my first verified sighting of it is this 1938 appearance in Terror of Tiny Town. Whether the two cabins seen in these top two photos are in fact the same building is a matter for some debate. These two angles are comparable, though not exact. In the above shot, the background includes Devil's Doorway (the stone cluster just behind the cabin) and Cactus Hill. The chimney clearly changes location between this shot and the 1940 appearance, but that's not unheard of. I do have a problem with the location of the window next to the chimney in the above shot, which seems farther from the corner of the building than the window in the top shot.
Here's another early appearance by the Gorge Cabin, in the 1940 serial Adventures of Red Ryder. The cabin appears here without the wooden add-on seen in the top photo, from Billy the Kid in Texas the same year. That pinpoints the addition, indicating it must have been done in 1940.
One more view of the cabin, this one from The Son of Davy Crockett (1941). The wooden addition was in place at this time, but isn't seen in the shot (it would be just off camera, to the left), and is only seen in partial glimpses in the film. It's unclear whether it was the intent of the filmmakers to avoid showing that addition.
The Gorge Cabin can be seen in a number of other productions as well, including Billy the Kid Wanted (1941), Outlaws of Boulder Pass (1942), Ride 'em Cowboy (1942) and Death Rides the Plains (1943).
It's worth noting that a couple of completely different cabins can also be seen in the Upper Gorge, in the same general area as the main Gorge Cabin, at different times — one very early cabin (circa 1933) and one much later cabin (circa 1960).
The Early Gorge Cabin — a small, crude wooden structure — turns up in Unknown Valley (1933), as seen here.
The Late Gorge Cabin, seen in One Foot in Hell (1960) and shown in the above photo, is probably a partial structure — missing one or two walls — as it appears to have been used for interior shots in the film, as well as for exteriors. It was part of a set that also included a stable, which is partially seen in the foreground in the above shot. The screen shot also shows part of Crown Rock, at far left, and the Devil's Doorway cluster, behind the cabin. The rocks seen here are all still in place, among the condos off Redmesa Road.
Another shot from One Foot in Hell, this one is shot from the interior of the Late Gorge Cabin, which may have only been in place for this one movie. With the door open, we can see Crown Rock outside, proving that the shoot was done on location. That means the cabin probably had some missing walls and was effectively a soundstage rather than an actual cabin, as it wouldn't have been possible to pull off this shoot inside the confines of a small room.
