You have Kurtyka/Schauer for "1994 & 1995" but they did their climb in 1985.
Bonatti 1958 route is NE ridge, not N.
Spanish 2008 did not go to main summit, as originally reported.
Thanks Damien. Corrected.
the 2008 spanish climber name is Miguel Zabalza (not "Zabalaza") ;)
Thanks for the info. I will change it right now!
Appears to be a couple more climbs (1997, 1999) listed on the Wikipedia page http://en.wikipedia.org/wiki/Gasherbrum_IV which largely references Alpinist Newswire. The coordinates seem to be a little off too, at least vs. the Google base-map. The Gasherbrum I page appears to also need as per this page: "Contrary to general belief Gasherbrum doesn't mean "shining wall". The name comes from the Balti words rgasha, which means beautiful and brum which means mountain."
Coordinates corrected. Info Source: High Asia 5700/500 list, by Jurgalski and de Ferranti. 35°45'45" 76°36'57" Converted to decimal.
The missing Korean ascents added.
I also changed the info on the GI page. I was one of those which believed Gasherbrum meant shining wall, but was later taught that wasn't the case. I had forgotten to change that on the GI page.
Solferino have published a new book (2018) by Bonatti La Montagna Scintillante that tells the story of the ascent of G4 in 1958.
Very interesting. Thanks for this info. I may looking for this book myself :)
