The Times reports that one of Lonely Planet's most experienced travel survival writers is missing in a remote mountain region of Tibet. Clem Lindenmayer, who has contributed to a number of books published by the travel guide organization, including a popular guide to surviving in China, disappeared more than a month ago while hiking alone near Minya Konka mountain, also known as Gongga Shan. The most recent contact with Lindenmayer took place on May 2 when he sent an e-mail to his family in Melbourne from Kangding, a city in Sichuan province in southwest China, near the unofficial Tibetan border.

Lindenmayer, 47, who is from Australia, has written for the travel publisher for more than a decade. He has contributed to books on climbing in the European Alps, walking in Switzerland, trekking in Patagonia and hiking in the United States.
