Francisco Coloane Coastal and Marine Protected Area, a sanctuary for humpback whales, is located in this area. This part of the strait lies on the elongated Magallanes-Fagnano Fault, which marks a plate boundary between the South American Plate and the Scotia Plate. This fault continues southward under Almirantazgo Fjord and then below Fagnano Lake.[47] Possibly, new tourism industries could be established in the eastern part of the strait for watching southern right whales,[48] as the number of observations in the area has increased in recent years.[49][50]
