5月30日上午，2005年珠峰登顶测量队和中国女子登山队的至少30名队员成功突破了恶劣天气的限制，花费7小时38分钟登上了世界之巅珠穆朗玛峰，并在峰顶停留77分钟。据了解，他们是今年珠峰攀登季节的第一支登顶队伍。外电报道如下：At least 30 climbers scaled Mount Everest on Monday, exploiting a break in treacherous1 weather to reach the world's highest peak, officials said.
They were the first to reach the 8,850-meter summit from the Nepalese side during this year's climbing season, which ends Tuesday, said Rajendra Pandey, a Mountaineering Department official.
At least two climbers have died in previous attempts this year, as strong winds and snowstorms have made climbing conditions miserable2, forcing climbers to remain at the base camp for weeks.
