In 1993, a 40-member team of the Indian Army from the Corps of Engineers was given special permission. The aim of the expedition was multifold – to carry out an ecological survey, clean up the garbage left by previous expeditions, and attempt the summit. The team included a number of wildlife scientists and ecologists from Wildlife Institute of India, Salim Ali Centre for Ornithology and Natural History, World Wide Fund for Nature and Govind Ballabh Pant Institute for Himalayan Environment and Development amongst others. The expedition carried out a comprehensive ecological survey and removed from the park, by porter and helicopter, over 1000 kilograms of garbage. Additionally, five summiteers scaled the summit: Amin Naik, Anand Swaroop, G. K. Sharma, Didar Singh, and S. P. Bhatt.
