译者直接将stone birch翻成“石桦”了，可能在生物学上有专用的名字。

The stone birch is the main tree of the Kamchatka Peninsula. These trees are unbelievably enduring. They had already been full-grown when Cossacks came to this place for the first time. And now every summer thousands of tourists admire this beautiful tree.

古老的石桦是勘察加半岛上的主要树种，这些树具有不可思议的耐力。早在哥萨克人第一次踏上这片土地的时候，他们就已经生长完全了。现在，每年都有数以千计的游客来一睹他们的风采。
