Available from November 2024, in physical format only (paperback), The Relative Mountains of Earth: The Ribus is an epic work which lists all 7150 Ribus across the entire planet, covering peaks in all seven continents. The Ribu concept was originally created by Gunung Bagging co-founders in 2009 but this publication is mainly the result of work undertaken since 2019 by an international team and includes a large list of collaborators and contributors. The book contains photographs, vivid stories and articles. It is published by Pedantic Press.
