Have you ever noticed that many old-growth cedars are hollow? That’s because younger trees may not have developed the self-protecting oil yet, so the heartwood rotted. As the tree develops, it develops the oils it needs to stave off bugs and fungus, making for a strong shell but a hollow core. That’s great news for critters of various kinds that like to nest or hide inside.
It was also great news for photographers in at least one instance. Charlie Poxleitner taught Civilian Conservation Corps students photography. This is a picture of their darkroom near Avery. The darkroom was inside the hollow of a cedar tree. The picture is probably from the mid-1930s and is part of the Idaho State Historical Society Digital Collection.
