The region that would be eroded the most would be those at the slopes of the mountain. When heavy rainfall comes, the soil in these regions gets soften thus being forced down forming a run-off due to the force of gravity. These eroded soil would eventually continue to the valleys thus causing landslides.

Thomas could maybe look back through his day and see where he put them
