Now these days, with so many people hiking around, it's pretty hard to find a new cave, so you can imagine how excited we were to find three new caves within sight of Oregon's largest city and realize that they had never been explored or mapped before.
时下，出外远足的人是如此之多。 发现一个新岩洞还真不容易。 这样你就可以想象当我们发现了三个新岩洞时 是多么的兴奋。 尤其是在俄勒冈州最大的城市发现它们 还没有人探索过这些岩洞， 或者绘制一幅地图。
