How did the mountains on the oregon trail influence the timing of pioneers’ travels? a.) the pioneers wanted to avoid times when there was snow in the mountains. the pioneers wanted to spend as much time as possible enjoying the mountain scenery. b.) the pioneers crossed the mountains in late fall when the trees were bare and the views were good. c.) the pioneers were rugged people who were not impacted by the terrain they crossed at any time.

The correct answer is "A".

The Oregon Trail was one of the first routes that opened the west to the many immigrants that would come from the east in the years to come. It connected the Missouri river with the valleys of what is now the state of Oregon, crossing the states of Kansas, Nebraska, and Wyoming.

Due to the harsh weather conditions that could appear in the mountains during the winter, the pioneers preferred to avoid crossing this part of the trail during winter, as unexpected weather phenomena could bring problems to the expeditions.
