The Regzen family outside their ger with all of their possessions, Ulaanbaatar, Mongolia. Published in Material World pages 40-41. The Regzen Batsuuri family lives in a 200 square foot ger (round tent built from canvas, strong poles, and wool felt) on a hillside lot overlooking one of the sprawling valleys that make up Ulaanbaatar, Mongolia. They live in a squatter's area, as do thousands of other Mongols who moved here from the rural countryside.
