I spent 5 weeks this summer traveling and mountaineering in Central Asia, primarily in the Tien Shan Mountains. Maier's guidebook, Trekking in Russia and Central Asia, was extraordinarily helpful for planning my travels and choosing destinations while travelling. It provided the essential information I needed to get into mountains. The maps and trek descriptions were almost always accurate, and the glossary in the appendix was very useful for breaking down language barriers. I'd rely on it again for future trips.
