The North Face, a long time expedition sponsor and well known equipment manufacturer, has released their 2006 Expeditions list. You will also find lists of previous expeditions on the same page as well.
Included on the list are such awe inspiring adventures as Peak Bagging in Bolivia, exploring the Ancient Caves of the Kingdom of the Mustang in Tibet, and a first ascent on South Face of Chimante, "a 2500 ' big wall on an unclimbed tepui deep in the heart of the Venezuelan jungle." All of these expeditions sound like an incredible experience to me. Hey North Face, hook a guy up, will ya'? :)
