We left Ashgabat around lunchtime in a convoy of three 4WD cars, packed with tents, sleeping bags, food, water, and, of course, many bottles of Vodka. We were heading to the site of a Soviet mining accident in 1971 when Russian geologists were drilling for oil. They found gas instead, and the drilling rig collapsed into a crater. The gas was expected to burn out within days, yet 40 years later it is still burning brightly.
Khiva, like Bukhara, was a powerful city state on built on an old oasis between the Kyzl Kum and Kara Kum deserts. It grew to become a major trading post on the Silk Road, building up a specialty in slave trading. Khiva continued to grow and developed a small empire, including much of modern day Turkmenistan, before it was overcome by Russian forces in 1873. With the formation of the Soviet Union it was included rather strangely in Uzbekistan, despite its people being mainly Turkmen in origin, and its history intertwined with that of Turkmenistan.
