How did the Blue Ridge mountains slow growth in the western part of Virginia?

The Blue Ridge Mountains created a natural barrier that hindered transportation and communication, making it difficult for settlers and traders to move westward into the more fertile lands beyond. The rugged terrain and steep slopes limited the development of infrastructure, such as roads and railways, which were essential for economic growth and expansion. As a result, the western part of Virginia experienced slower population growth and economic development compared to the eastern regions. This geographical obstacle shaped settlement patterns and influenced the state's overall growth trajectory.
