The Karakorum is the wildest mountain range in the world. One of the spectacular mountains around this Baltoro glacier is the Trango “Nameless Tower”. It’s the biggest free-standing rock tower, and it’s just asking to be climbed. Edu Marín, with the help of his brother Alex and father Novato, attempts the second free ascent of the Eternal Flame route – 33 years after its first ascent by Wolfgang Güllich and Kurt Albert, and 13 years after Alex and Thomas Huber’s first free ascent.
