Beneath this facade lies a range which presents explorers with a grueling challenge. Hard rains are a daily occurrence and the resulting mud slides are every bit as dangerous as any avalanche. Most surface water is contaminated and unhealthy to drink. Although food is plentiful, the non-native will have grave difficulty distinguishing edibles from similar looking fruits which are toxic. Disease is also prevalent. In addition to these physical challenges, the range is home to a wide assortment of avian and reptilian predators.
