Roca Remolino
Roca Remolino is a submarine mountain in Chacao Channel, Chile, notorious for being a major hazard for traffic along the channel. Roca Remolino does not show up during low tides. When there are strong tidal currents in Chacao Channel the rock creates a whirl effect, drawing objects to it. Roca Remolino first studied by Francisco Hudson in the 19th century and was studied again 2005 to see the feasibility of putting one of the planned Chacao Channel bridge's pillars on it.
