从波特兰到黄石公园(16)-- Craters of The Moon 熔岩洞

去过夏威夷活火山的人都看过很多的熔岩,但是Craters of the Moon依然有很多景致是夏威夷很难看到的。其中最有特色的就是熔岩洞(LAVA TUBE)。

熔岩流动的时候它的上部首先冷凝变干成为坚硬的石头,而内部滚烫的液体熔岩还在继续流动。等到内部的熔岩流光之后,就剩下一个巨大的熔岩隧道。

走在熔岩区时,很难想象脚下有一个大空洞,甚至是大隧道。在Craters of The Moon,有一个区域可以让人们实地参观这些熔岩洞。有时,这些隧道或空洞塌陷,使我们有机会看到它们的存在。



最精彩的景致是印第安隧道(Indian Tunnel),游客可以实地考察一个部分完整的熔岩隧道。

熔岩隧道入口



在隧道内回头看洞口



熔岩隧道象个巨大的防空洞,望不到尽头,每隔一段有一个塌陷。走这段路最好带上手电。



过了一个洞口又是一个洞口,洞中高低不平的路不知何时是尽头,





天窗就在眼前,无奈爬不上去



终于看到了出口的光线,希望就在前方



这个乱石堆就是出口



从这个小洞里钻出来时有一种从险境中逃生的感觉



回头看出口,右下角的那个小洞



回程的路顺着木杆指示的方向走,



最后看一眼刚才经过的洞口



参观结束,收获不少。回程路上要小心,安全第一。在一个下坡转弯的处,看到了这样的情景
