Accessible only by packhorse—a rough, 15-mile ride up Boulder Basin—it's true wilderness, some of the wildest land in America.

驮马能行走的也只有顽石坝那15英里的路程。这里真是个荒野。它是美国为数不多的几个野生园区之一。

The striking construction relies onauthentic architectural principles as used in the dry-stone walls and theoriginal packhorse bridges that are found in the Lake District to hold it up.

这个桥梁的建造应用了真正的建筑学原理，比如石墙（不用灰泥只用石块构造的石墙）以及原始的驮马桥都是应用了这种原理。

But the humble push-bike is earning a reputation as a terrorist's packhorse.

但是小小的自行车（如今）却落得恐怖分子驮马的名声。
