FIRST DESCENTS OF SEVERAL HEADWATER STREAMS OF THE AMAZON
Laszlo Berty was a Hungarian rafter/kayaker who did several pioneering descents of rivers in Peru in the late 1970s, including much of the Marañon, Vilcanota-Urubamba, and Mantaro. Berty may have been a citizen of the USA.
It is difficult to find information on the late Laszlo Berty since he wrote little and little was written about him. However, it is clear that he was in Peru in the late 1970s with a raft or two and did the first modern raft descent of the upper Urubamba (through the Sacred Valley) and lower Urubamba sometime 1978 to 1980. According to John Wasson, Berty also had done the first descent of much of Río Marañon in 1976 or 1977, starting in Chagual or Balsas. Berty also paddled much of Río Mantaro and possibly other rivers in Peru and Bolivia.
DO YOU HAVE INFORMATION ON LASZLO BERTY?
I am preparing a book, First Descent of the Amazon, and would like to credit Berty for his pioneering first descents in the 1970s and early 1980s. If anyone has information on Berty or his descents, please contact me (Rocky Contos).
Berty deserves credit and a tribute!! Please help! [apparently he died several years ago]
