Aguja T48, Aguja Lise ("2"), "3 bis", Aguja Chata ("3"), Aguja Tenazas, Aguja Leo ("5").

General description.

The 1916 expedition from the Buenos Aires “Sociedad Científica Alemana” (Buenos Aires) named the two of seven summits located between Cerro Grande’s west ridge and Paso del Viento. The second one from the north was named Cerro Tenazas and the first from the south was named Cerro Murallón. Much later, in 1952, Frenchman Louis Lliboutry, cartographer and geologist of the expedition that completed the first ascent of Fitz Roy, grouped Cerro Tenazas and Cerro Murallón and called all seven summits Agujas del Rio Túnel.

Lliboutry saw five summits instead of seven and he numbered them from south to north. The first one in Lliboutry’s count (number "1") is what Kölliker called Cerro Murallón (later "rechristened" Cerro Murallon del Viedma to avoid confusion with the well known Cerro Murallon west of the Upsala glacier) was climbed by Carlos Comesaña and Ismael Palma who renamed it Aguja T48. Lliboutry's number "2" was climbed in 2016 and was christened "Aguja Lise". Lliboutry's number "3" was climbed in 2013 and was christened "Aguja Chata" and is in fact two towers one further west and south of the other. The second summit is listed here as "3 bis" and it is still unclimbed. Lliboutry's "4" is what Kölliker named Cerro Tenazas (after the likeliness of its double summit with a pair of tongs) and is also unclimbed. Lliboutry's "5" was climbed in 2016 and was christened "Aguja Leo".

As the names now stand, from south to north, from Paso del Viento to the west ridge of Cerro Grande are: Cerro Azara and a minor sub-summit called Cerro Bravo (not part of Agujas del Río Túnel), followed by the Agujas del Rio Túnel: Aguja T48 (formerly known as Cerro Murallon or Cerro Murallon del Viedma), Aguja Lise ("2"), "3 bis", Aguja Chata ("3"), Aguja Tenazas and Aguja Leo ("5").

The 1958 expedition led by Folco Doro Altan, that included Walter Bonatti and Carlo Mauri reached the col to the north of "2" during one of their exploratory trips.

Climbing history.

T48 - Comesaña-Palma. Argentines Carlos Comesaña and Ismael Palma climbed T48 in January of 1966. They accessed the base from the west, having crossed Paso del Viento and headed north on the Icecap. The climb was completed via the west face, which proved to have very bad rock that held pitons poorly and involved both ice and rock, with some sections up to 5+. The final pitches were mostly ice climbing and the summit mushrooms were climbed from the east. The descent involved ten rappels and 200 meters of down climbing (50˚).

They named the tower after an Argentine Airforce plane called Tango 48, which fell in Panama killing several army officers. The first ascentionists, courtesy of the Airforce, had traveled for free several times to climb in Peru and other locations in this very plane. More info about this plane here.

T48 - M23. In 2016 Quentin Lindfield (CA) climbed the east ridge. It involves 300m of fairly easy scrambling with a few harder sections. The rock is comparatively loose. Its a beautiful, easy route with great views. It is a great objective for a fitness solo, with minimal glacier travel. His was the second ascent of the peak.

Aguja Chata - Por donde empezar. In May 2013 Argentines Agustín and Juan Manuel Raselli with Ignacio Teerink did the first ascent of Liboutry's number "3", climbing a broad snow slope on the east face to reach the base of the north ridge which they climbed mostly on its east side. They christened their route "Por donde empezar." They believe this is one of the easiest towers of the Agujas del Río Túnel group, but point out that the vertical gain was much more than previously thought, with an estimated  450 meters. The climbing is mostly mixed and not overly hard technically although the bad rock quality make it a serious undertaking.

Agujas Lise - Leo - El dealer de la bicicleta & La vida boba. In early 2016, and approaching from the east, Julian Casanova and Tomás Müller climbed new routes on Lliboutry's #2 and #5, which they christened agujas Lise and Leo respectively. On Aguja Lise ("2") they climbed an obvious couloir to a col, then followed the north ridge, to drop west into an obvious gully, passing below a secondary-summit to tackle the main summit via the north ridge and the east face. They named the route "El dealer de la bicicleta" (500m 5 60˚), a name that refers to a local climber's first experience purchasing marihuana to then resell to a friend (with 10 grams in his pocket the poor fool felt like he was about to put El Chapo Guzman out of business...). On Aguja Leo ("5") they climbed an obvious ramp leading to the north east face, to then head to a col on the north ridge, and from there along the ridge to the summit. They name the route "La vida boba" (450m 5 60˚). In both cases they descended roughly the line of ascent, downclimbing or using avalakov's on the snow/ice sections.
