Roca Remolino
# Roca Remolino

Roca Remolino (lit. "Whirl Rock") is a submarine hill in Chacao Channel, Chile, notorious for being a major hazard for traffic along the channel. With its highest point at 20 m below sea level Roca Remolino does not surface up during ordinary low tides, but its top can occasionally be seen during extremely low tides. It is located at the narrowest part of the channel, about 700 m from the southern shore which is the nearest land point. When there are strong tidal currents in Chacao Channel the rock creates a eddies, drawing objects to it. Roca Remolino was studied by Chilean Navy officer Francisco Hudson in the 19th century. One of the Chacao Channel bridge's pillars is being built on top of Roca Remolino.
