From the author of the classic Arctic Dreams comes a vivid recollection of his travels around the world and the encounters that shaped an extraordinary life. Taking us nearly from pole to pole - from modern megacities to some of the earth's most remote regions - Barry Lopez gives us his most far-ranging and personal work. Spanning decades of travel, Horizon describes journeys to six regions of the world: from Western Oregon to the High Arctic; from the Galapagos to the Kenyan desert; from Botany Bay in Australia to finally, unforgettably, the ice shelves of Antarctica. Lopez also probes the history of humanity's quests and explorations, from prehistoric expeditions to today's ecotourism. He takes us to some of the hottest, coldest, and most desolate places on the globe, via friendships with scientists, archaeologists, artists and local residents, in a book that makes us see the world differently. It is the crowning achievement of one of the world's best travel writers.
