Natural dips and crevasses in the land can fill up with extremely light, powdery silt. These areas act like quicksand, easily trapping unwary creatures.
Effect: Silt pools are difficult terrain, and occasionally hide silt deep spots. They can also contain silt sink hazards.
Usage: Although smaller silt pools can blend into the surrounding terrain, the flat, liquid surface of a larger silt pool rarely goes unnoticed. Wading through a silt pool and risking silt deep spots might be the only path available.
