modified version of the Mummery tent. In 1920 Harold Raeburn discussed an improved design with a groundsheet attached and commented that ice axes were too short to be tent poles. He recommended that two bamboo sticks long should be taken to fit over the ends of the ice axes. These tents were among those used on the 1921 British Mount Everest reconnaissance expedition and two Mummeries were used at the East Rongbuk Glacier camp before and after the culminating ascent to the North Col.
