 Among them, adventurers such as Yossi Ghinsberg, who in 1981 participated in a failed expedition with Karl Ruprechter, Marcus Stamm and Kevin Gale, who were lost and separated.Gale was rescued by Uchupiamonas or "Josesanos" (Joshuaians) and was transferred to Rurrenabaque, where he recovered and began the search for Ghinsberg, who was rescued after three weeks of surviving alone and without equipment in the jungle.The friendship between Ghinsberg and the Josesanos led them to generate an ecotourism project aimed at improving the quality of life of these indigenous people and conserving biodiversity.
