{"product_id":"valles-caldera","title":"Valles Caldera","description":"About 1.25 million years ago, a spectacular volcanic eruption created the 13-mile-wide circular depression now known as the Valles Caldera, located in northern New Mexico. This revised \u0026amp; expanded edition marks the twentieth anniversary of the Valles Caldera Preservation Act, a visionary piece of legislation that transferred to the public domain a privately owned ranch (signed in 2000 by President Bill Clinton). The preserve was assigned to a board of citizens appointed by the president to manage it as a self-sustaining preserve. The experiment in semi-private land management ended in 2014 as the Valles Caldera was legislatively reassigned to the National Park Service.","brand":"Gardners","offers":[{"title":"Default Title","offer_id":57483359191413,"sku":"9780890136577","price":45.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/7193\/3106\/files\/9780890136577.jpg?v=1786178500","url":"https:\/\/backstory.london\/products\/valles-caldera","provider":"Backstory","version":"1.0","type":"link"}
