PIG. 42. The result of raindrop splash erosion. (The rod is painted in one 

 inch sections.) Where the soil is protected by stone or root or vegetation, 

 erosion is foiled. Here, surface flow had little effect on the soil in place: it did 

 not wash away the pedestals. The churning- and digging- by the raindrops 

 impact did the damag-e. Surface flow merely carried away what the drops 



loosened.
