Recent findings (audit lane, verbatim)

Aconcagua — The claim that Aconcagua is the third-most topographically prominent peak in the world after Mount Everest and Denali is incorrect; it is actually the second-most prominent peak after Mount Everest, with Denali being third.

Aconcagua — The statement that the oldest verified person to climb Aconcagua was Scott Lewis, who reached the summit at age 87, is inaccurate; the oldest verified person is Juan José Mendoza (age 87 in 2020) or other older climbers, not Scott Lewis.

Hallasan — The summit elevation of Hallasan is 1,950 meters, not 1,947 meters.

Hallasan — The last confirmed eruption of Hallasan was around 5,000 years ago; the 1007 CE event is not considered a confirmed eruption.

High Atlas — The High Atlas extends to the Moroccan-Algerian border: The range ends before the border, with the easternmost part of the High Atlas terminating in the region of the Moulouya River valley and the Middle Atlas, not reaching the Algerian border.

Hoggar Mountains — The Hoggar Mountains are stated to be 'along the Tropic of Cancer', but they are centered just north of it, not directly on it.

Hoggar Mountains — The area given as 'approximately 50,000 km²' is typically for the Ahaggar Cultural Park, not the entire mountain range, which is a factual imprecision.

Illimani — The first recorded ascent party is incorrect: it lists Jacques de Lépiney, but the actual first ascent party was led by J. de Grumkow and included J. C. Ocampo, not Jacques de Lépiney.
