There has been a major effort from EvK2CNR to clean up the Boltoro glacier in the last few weeks. They state that there has been 4 tonnes of waste that has been removed. This waste will be transported to Askole and burnt.
There have also been 8 toilets that will be installed near K2.
It was not an easy trek to K2 though for this expedition. It was hard to get porters to carry heavy materials to the Boltoro glacier. Then there was a broken bridge near Askole.
