This stunning visual diary by Sonia Szóstak documents a trip taken with two other friends through Bolivia and Peru. From the Eduardo Avaroa National Park in Bolivia to the peak of Peru’s Ausangate mountain, Szóstak reveals landscapes carved by sun, wind and lava — strange terrains seldom conquered, and breathtaking in its beauty. “Altitude translates to simplicity,” the photographer says of her trip. “The higher we go the less details there are.” Follow her on Instagram.
