Geology of Lesotho yield and frequent springs. Steep terrain, rain and snow melt mean that Lesotho has a high risk of landslides. Lesotho has extensive diamond deposits in both kimberlites and alluvial gravel. The country has the highest concentration of kimberlite bodies in the world—a total of more than 400, including 343 dikes, 39 pipes and 23 blows.
