Which was the only feasible passage through the Rockies for emigrant wagons?

Answer 1

The only feasible passage through the Rockies for emigrant wagons was the South Pass, located in Wyoming. This low mountain pass provided a relatively gentle route through the difficult terrain, making it accessible for wagon trains heading west during the 19th century. Its significance was further highlighted during the California Gold Rush and westward expansion, as it became a key part of the Oregon Trail and other emigrant routes.
