It is an area filled with red sand and dirt and sheltered by trees, located in a slight dip just outside of the ThunderClan camp. A river once ran through the hollow before drying up and leaving only a stream beyond the hollow.It is used by the ThunderClan wolves for aspects of training, particularly mentors drilling their apprentices in fighting and hunting moves. Due to the soft ground, training wolves are unlikely to get hurt while fighting. It can also serve as a well-known meeting place for warriors.
