The archaeological findings made on Coropuna indicate that the Inca may have reached the summit. Annie Peck and Hiram Bingham III each reached a summit of Coropuna in 1911; Peck raised a banner saying Votes for Women on the summit she had ascended, which was slightly lower than the one reached by Bingham. This banner action was part of the women's suffrage campaigns that were taking place at that time, and meant to illustrate that women were just as capable as men of physical deeds. Since then, other summits of the mountain have been ascended as well.
