Kyrgyzstan (formerly Kirghizia) is a rugged country with the Tien Shan mountain range covering approximately 95% of the whole territory. The mountaintops are perennially covered with snow and glaciers. Kyrgyzstan borders Kazakhstan on the north and northwest, Uzbekistan in the southwest, Tajikistan in the south, and China in the southeast. The republic is the same size in area as the state of Nebraska.
