The Gallatin Way, a picturesque route heading south through the canyon to the west gate of Yellowstone, boasts a history covering more than a century of exploration, homesteading and development. Early pioneers and adventurers endured a rugged and unforgiving terrain where today's travelers speed along a modern highway. One might expect to see dramatic shifts, yet little change is evident in some areas, while others teem with contemporary luxuries.
