The volcanic terrain, characterized by rough, barren ground, sharply contrasted with the expansive lagoons and oases. These natural features demonstrated the resilience of life, supporting various species of flora and fauna.

Numerous animals have adapted to this unique environment. Small frogs leapt from the remnants of tiny lagoons, while condors, with their impressive wingspans, cast noticeable shadows on the ground as they soared high in the sky. The lagoons provided essential food and nesting places for various birds. Wild horses grazed on the green grass nourished by rivers that sometimes flowed beneath the bare sand.

Navigating the sandy terrain proved challenging; every two steps uphill felt like sliding one step back. The sand infiltrated our clothes, shoes, and skin, making us feel like sandmen when blowing our noses. Dominating our journey were two significant volcanoes, Azul and Descabezado Grande. Descabezado Grande, also known as the "beheaded volcano," stands at 3953 meters above sea level, making it the second-highest mountain in the Maule region. Climbing these volcanoes is now on my bucket list. I had the opportunity to hike up Colmillo del Diablo, a prominent peak above the El Bolson campsite for now.
