Radoslaw Koscinski's symbolic gravestone in the Peruvian Andes. On Cacanapunta Pass, at an altitude of about 4,500 m, there is a small stone plinth with a metal cross and a plaque and inscription in Polish:

"To the memory of the Polish alpinist Radoslaw Koscinski 3. VIII. 1971 - 22. VIII. 1998. He died searching for the source of the Amazon River - Maranion. Colleagues of "Canoandes" Inc. August 2000".

A plaque and cross commemorate the tragically deceased Radoslaw Koscinski, one of the lesser-known participants in the Polish exploration of the sources of the Amazon River. Kościński died in 1998, during an expedition to find the sources of the Rio Marañón, considered one of the main arms of the Amazon. The site where the commemorative cross was erected is near the Caliente River, whose waters through its numerous tributaries join the Marañón.
The history of the gravestone is part of the broader context of Polish research and expeditions in search of the sources of the Amazon. Poles have played a key role in this search - the best-known figures include Edmund Bielawski, Piotr Chmieliński (a member of the Canoandes expedition, the first man to navigate the Amazon from its source to its mouth), and Jacek Pałkiewicz, who in 1996 headed an expedition recognised by the Peruvian government as the one which finally identified the Amazon's sources in the Nevado Quehuisha area.
Radosław Kościński, although less well known, belonged to the same circle of travellers and explorers for whom the Andes and the Amazon became a space of passion, research and - in his case - also tragedy.
