Hiking the Cosmic Spine: Trails Along Meteorite Craters and Impact Zones is a one-of-a-kind journey across Earth's most awe-inspiring scars-formed by celestial collisions that changed the course of geology, evolution, and time itself.Told in immersive first-person narrative, this guide takes you step-by-step along five remarkable hikes, each threading through the remnants of ancient meteorite strikes: from the drunken forests of Alaska and thawing Siberian permafrost, to the drowned Chicxulub rim in Mexico and the exposed planetary dome in South Africa. Blending geology, sensation, and reflection, each trail becomes a meditation on deep time, survival, and our place beneath the stars.More than a hiking guide, Hiking the Cosmic Spine is a trail journal, field companion, and cosmic memoir for those who walk not just to move forward, but to connect backward-through ice, stone, silence, and stars.Whether you're a seasoned trekker, geology enthusiast, or a curious soul drawn to the profound and the peculiar, this book invites you to walk Earth's hidden fault lines between worlds.
