In the spring of 1968, the first documented mountaineering party succeeded in crossing the icefield. Ten people were involved in the crossing, which went from Chernof Glacier east to Exit Glacier. Expedition members included Bill Babcock, Eric Barnes, Bill Fox, Dave Johnston, Yule Kilcher, his son Otto, Dave Spencer, Helmut Tschaffert, and Vin and Grace (Jansen) Hoeman. As noted above, Yule Kilcher, Dave Johnston, Vin Hoeman, and Grace Hoeman were veterans of previous attempts; of the ten, only four–Bill Babcock, Dave Johnston, Yule Kilcher, and Vin Hoeman–hiked all the way across the icefield. The expedition left Homer on April 17, bound for Chernof Glacier; eight days later, they descended Exit Glacier and arrived in Seward. Along the way, the party made the first-ever ascent of Truuli Peak, a 6,612—foot eminence that protrudes from the northwestern edge of the icefield near Truuli Glacier.
