HORCONES INFERIOR

 

Event description

 

Based on the image of December 24, 1984, a wave of ice free of supraglacial drift advanced 6,100 m from the head of the glacier at an altitude of 5,350 m a.s.l. The glacier front motion probably started in 1984. On the image of February 22, 1986 the glacier surge advanced 3,675 m between 1984 and 1986 and reached a lower topographic position (100 m) than it did in 1976 (Unger and others 2000). Between 1986 and field photographs from February 1990, the glacier front advanced 560 m. The surge stopped in 1989, and the glacier surface was intensely crevassed.
