A record climbing season has left parts of Mount Everest looking like a rubbish dump with discarded tents and sanitation pads with one experienced local climber describing the mountain as the "dirtiest" he has ever seen it.
Climbing guide Tenzi Sherpa recently completed a climb and said people left behind tents, empty gas bottles, bowls, sanitation pads and plastic at Camp Four on the South Col, 7,906 metres above sea level.
He's been taking climbers up the mountain for four years.
