Oh's 2009 summit of Kangchenjunga has been questioned, throwing her accomplishment into doubt. The dispute stems from a photograph said to have been taken by Oh at the summit which is too blurry to confirm exactly where she stood when she took it. The photo is the only visible evidence she has of her ascent. After doubts were first raised in Korea, Oh held a press conference in which she tearfully remarked that the blurriness was unavoidable due to fog and a violent snowstorm. One of the Sherpas who accompanied her on the climb assured the media that he knew the layout of the mountain well from previous climbs and that Oh had indeed made the summit.
