Gully 0 ▲ Graham's Island 31 minutes ago · Nature · hide · 0 comments One of many gullies that run down the side of Kohala Mountain. When it rains at the top, which it does often, water funnels down the gullies to the ocean. Heavy rain, such as during the recent hurricane, can cause flash floods and dump a lot of sediment into the ocean. If the rain is heavy enough, it can also cause considerable property damage.
