The Triangle X Barn is part of the outbuilding complex of the only dude ranch still in operation within Grand Teton National Park -- the National Park Service licensed Triangle X. Around 1928, J. C. Turner of the Triangle X Dude Ranch moved dovetailed logs from neighbor John Fee's partially completed homestead cabin to the Triangle X Ranch where the logs were used to form the first ten courses of Turner's new barn. The barn is a graphic visual representation of divergent notching types; a reminder of the extent to which resources are reused in a frontier economy; and an example of the close connection between vernacular, ''pioneer,'' architecture and its dude ranch successor.
