The third of Michael Palin's travel adventures for BBC Television covered 50,000 miles and all of the 18 countries that border the Pacific Ocean. Basil Rao's photographs bear witness to the wide diversity of landscape, culture and people encountered on the journey. The Pacific Rim is one of the world's most volatile areas, with economies that are expanding faster than anywhere else on earth - and here the earth itself is in a constant state of flux. Not for nothing is the Pacific coastline known as the Ring of Fire - volcanoes mark Palin's journey like stepping stones, and he climbs one which has recently erupted and is still smoking. He negotiates mountains and plunging gorges, crosses glaciers, dodges icebergs, follows great rivers such as the Yangtse and the Amazon, and confronts the notorious Cape Horn and the wild and windswept beaches of western Alaska. The people Palin meets include one of the few remaining survivors of a Siberian Gulag camp, head-hunters in Borneo, and Japanese monks. He eats maggots in Mexico, rustles camels in the Australian desert, lands a plane in Seattle, and sings with the Pacific Fleet choir in Vladivostock.
