Route Notes	Gegar Tamang's baggage lost by airline and bought some items in Namche but plastic boots too slippery on route. 15th food supply almost finished in C1 on return there and running out of gas to melt water there. Boersma feeling well but these problems meant unwise to continue up mountain under these circumstances and called off climb 15th night. Every day good weather in morning.
