Nevado Ulta, west-northwest face. Previously unreported and scarcely known is an August 1985 ascent of an ice-and-mixed line, thought to be on the far left side of the west-northwest face (called the northwest face in the photo on p. 275 of the 2001 AAJ; also shown as the shaded face on the right in the photo on p. 302 of the 2003 AAJ). Chris Hassig and Jonathan Stevens climbed a long couloir with technically difficult mixed ground, continuing to the summit. They climbed the route in a long day, made a forced bivouac, and descended the next day. While rappelling Hassig fell to his death and took the ropes with him, but Stevens survived.
