Clambering over the top boulders, I find a wedge of rock to shield me from the chilling wind, and collapse. For some time, I look long and hard at the three granite towers facing me: Torre Norte, Torre Central, and Torre Sur. They loom above a perfect turquoise lake like incisors, stubbornly resisting the erosional forces of nature, tearing the gauzy white fabric of cloud around them. www.patagoniaon2wheels.blogspot.com
