Patagonia refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands, and steppes to the east.
Messier Channel is a channel located in Patagonia, Chile. It trends north–south between Wellington Island and other Pacific islands and the continent and is bounded on the north by the Gulf of Penas. Southward the name of this inside passage changes first to Angostura Inglesa (English Narrows) and then to Paso del Indio.
Messier Channel is surrounded by the Bernardo O'Higgins National Park and the Katalalixar National Reserve. The channel is named after Charles Messier, who was a French astronomer. It is a fjord in the Scandinavian sense of the word. A depth of 1,358 m has been measured in the north part of this channel, making it one of the deepest fjords in the world. The world’s deepest fjord, known as the Skelton Inlet in Antarctica, is 1.9km below sea level at its deepest point.
The Fallos-Ladrillero-Picton Channel combination is an optional route to the Messier-Grappler-Wide Channels route between the Golfo de Penas and the Trinidad Channel.
Just north of Angostura Inglesa (English Narrows), is the wreck of MV Capitán Leonidas, a small freighter that ran aground on the Bajo Cotopaxi (Cotopaxi Bank) in 1968. The hulk provides warning as both a shipwreck and a lighthouse.
