 The Furtwängler Glacier is located near the summit of Kilimanjaro . Between 1976 and 2000 , the area of Furtwängler Glacier was cut almost in half , from 113 @,@ 000 m2 ( 1 @,@ 220 @,@ 000 sq ft ) to 60 @,@ 000 m2 ( 650 @,@ 000 sq ft ) . During fieldwork conducted early in 2006 , scientists discovered a large hole near the center of the glacier . This hole , extending through the 6 m ( 20 ft ) remaining thickness of the glacier to the underlying rock , was expected to grow and split the glacier in two by 2007 .
