”The day following another five- or six-thousand foot drag brought us to a tiny notch on a secondary ridge of the Nilgiri massif. This pass, so insignificantly-seeming among the vastness of the mountains, proved to be one of the most important in the history of the Himalayan mountaineering, for it was here that on 26th [actually 27th] April 1950, Couzy, Oudot and Schatz discovered the amazing traverse of the walls of the Miristi gorge, without which Annapurna would never have been climbed” (Lionel Terray, Conquistadors of the Useless). This is the famed Pass Of April 27 (4310m).
