how did pioneers have to prepare for the journey west and what obstacles did they face along the way​

Pioneers would take with them as many supplies as possible. They took cornmeal, bacon, eggs, potatoes, rice, beans, yeast, dried fruit, crackers, dried meat, and a large barrel of water that was tied to the side of the wagon. If the pioneers could take a cow, they would.

Obstacles included accidental discharge of firearms, falling off mules or horses, drowning in river crossings, and disease. After entering the mountains, the trail also became much more difficult, with steep ascents and descents over rocky terrain. The pioneers risked injury from overturned and runaway wagons
