Incredibly high temperatures. Decorative volcanic `bombs` can still be found

To think that thousands of years ago, right where my feet were standing, lava had spurted out at incredibly high temperatures. Decorative volcanic `bombs丒can still be found among the debris. The stunted vegetation resembled that of Provence in France but without sunshine.
我所停憩的地面是在好几千年前喷出极高热的岩浆经冷却而形成的，在这里仍可发现岩渣中的火山弹，点缀其间；由于光照不足，那里的植物发育不良株杆矮小，那景象使我想起了普洛旺斯那样的地方。
