Ascent days. On February 18, 2025, we arrived at the base of this immense mountain. The following day, we climbed the monolith of Ben Amera, a massive granite rock formation rising 560 meters above sea level and the tallest monolith in the Sahara. Located in northern Mauritania near the border with Western Sahara, Ben Amera is a geological wonder shaped over millions of years of erosion, standing as one of the most impressive inselbergs in the world. This natural colossus, composed of ancient Precambrian granite, holds both cultural and historical significance, with the surrounding area dotted with prehistoric petroglyphs and remnants of past civilizations.
