Rawles who ascended the south ridge.{{cite journal | title = Elizabeth Woolsey, 1908-1997 | journal =American Alpine Journal| date=1998| issn= 0065-6925 | first =Virginia | last = Huidekoper | isbn= 978-0930410780 | volume =#72 | issue = 40 | access-date =19 October 2024 |url = http://publications.americanalpineclub.org/articles/12199840600/Elizabeth-Woolsey-1908-1997 }}
