Talk:Aiguille de Bionnassay

Date of First Ascent
To avoid future disagreement based on different secondary sources, it should be noted that the first date of the Bionnassay ascent was 28th July, not 25th July 1865, despite some key secondary sources and mountain guidebooks such as Dumler and Burkhardt's The High Mountains of the Alps (1994) stating the 25th. Grove's published account of the ascent in the Alpine Journal, page 322 clearly states they made plans on the 27th, setting out the following day. Parkywiki (talk) 15:03, 10 November 2015 (UTC)
