Laguna 69 sits at the base of a giant glacier in the Cordillera Blancas. Its elevation is at approximately 15,000 feet, which beats anywhere in the continental United States by a good 500 feet. Somehow, no one in Huaraz seemed to be impressed by this.To give you an idea of how incredibly high Laguna 69 is, once Lia and I jumped out of a plane to skydive from the highest altitude they were legally able to fly us, and it was STILL lower than Laguna 69. I knew this would would be no walk in the park, but I had no experience hiking at such a high altitude before. I was about to get a crash course.
