a tool with a long handle and a metal head that is pointed at one end, used by climbers to fix into ice or snow and hold or step onto

I was amazed at how secure the ice axe was once it had been planted in the snow. 我很惊讶冰镐一旦被插入雪中会抓得那么牢固。

Some routes may require an ice axe or crampons. 有些路线可能需要冰镐或带钉铁鞋底。
