In 1974 the glacier was about 5 km long and is known to have extended for at least 35 km during the Pleistocene. According to another report, Kolahoi is a hanging glacier and hollowed inside. It is a matter of great concern for Kashmir Valley. Many expeditions have failed here.
In September 2018 a group of nine trekkers went on an expedition to summit the Kolahoi Peak. After successfully summiting the peak, the group was caught in rock fall near Burdalaw region on the glacier during their descent, due to which team lost two of its members: Adil Shah, founder of Alpine Adventures group and Naveed Jeelani who was a junior administrative officer from Srinagar. Their bodies were later retrieved from the glacier after two days due to bad weather.
