ガニソンから次の場所へ向かう道中にも、美しい景色が広がっていました。そんな景色を見ながら再確認したことがあります。
Beautiful scenery awaited us even along the way to the next destination from Gunnison. Then I confirmed one thing while I was gazing at such sights.

マグマが固まった後の結晶の硬さと堆積岩の柔らかさで山の形が決まるんだ。
The shape of the mountain is defined by the crystallized minerals from magma and the softness of sedimentary rocks.

だから尖った岩肌ができたり、滑らかな岩壁ができたりするんだ。
That’s why we see pinnacles of rock in one place, but the smooth face of other rocks in other places.

45度の熱と マイナス20度の氷結も道具なしで巨岩を分断し、山間を流れる川と空を舞う風は、岩が硬くても柔らかくても岩を削り取っていく。こうして山の顔ができるんだ。
The temperature extremes of a baking110F on the high end and a frozen -10F on the low end can also crack through a gigantic rock without using any tools. And don’t forget about rivers running through mountains and blowing winds. They also erode even the hardest of rocks. This is how the faces of mountains are created.
