The first concern for pioneers looking to conquer the Oregon Trail was forming a group — or “train” — that would travel the route together, sharing vehicles, drivers, tools, food, and medical supplies. By then, those preparing to make the journey would have sold off their homes, businesses, and anything they couldn’t bring with them, and invested in supplies for the journey. However, some families chose to make the trek on their own after making preparations that could take years.
However a train was organized, it was vital that it set off from the East at the correct time of year. If the pioneers set off in the winter months, their carriages would become immobilized by snow and blizzards, while they would be at risk of succumbing to the cold. Many routes cut through high altitude mountain passes, where snow and ice remained for many months of the year. Travelers were obliged, therefore, to begin the journey in the spring, although that would mean facing intense heat and dust clouds during the summer months.
