I was walking down a slight incline in the rock pit, and there was loose gravel that gave way under my right foot, resulting in me falling to the ground from standing height. When I fell I landed on my left knee, and my right wrist. My left knee had minor scrapes and cuts, and my right wrist received a hard impact and resulted in lots of pain and swelling.
