They don't really have much out there, but bat guano.

除了蝙蝠鸟粪之外，他们实际上并没有太多东西。

The reason they were discovered is because people began mining the land for bat guano.

它们被发现的原因是因为人们开始在这片土地上开采蝙蝠粪便。

As they were looking for this bat guano, they discovered the Carlsbad Caverns, or what became known as the Carlsbad Caverns.

当他们在寻找这种蝙蝠粪便时， 他们发现了卡尔斯巴德洞穴，或者后来被称为卡尔斯巴德洞穴的地方。

Unfortunately, most of the artifacts were taken by explorers or treasure hunters or simply destroyed when the cave was briefly used for mining bat guano for fertilizer.

不幸的是，多数手工艺品或被探险者、寻宝者拿走。或是在这个洞穴被短暂用作蝙蝠粪肥产地时被破坏。

You can also see more than a million Mexican free-tailed bats each summer which live in the caves, and I suppose if you want to take a little bat guano as a souvenir, you could do that as well.

每年夏天你还可以看到超过一百万只生活在洞穴中的墨西哥无尾蝙蝠， 我想如果你想带一点蝙蝠粪作为纪念品，你也可以这样做。
