North Twin, north face, House-Prezelj. In early April 2004 American Steve House and Slovenian Marko Prezelj made the third ascent (Lowe-Jones, 1974; Blanchard-Cheesmond, 1985) of the daunting 4,500' north face of North Twin, one of the great prizes of North American alpinism. Their route takes an independent start before joining the Lowe-Jones in the upper half and finishing via that route. As the ascent was essentially a continuation of the 2003-04 winter climbing season, we are covering it in this year’s Journal. See House’s feature article earlier in this Journal for details.
