We set up camp on a sandy flat beside a pool. What a swimming hole! My brother and I swam, diving and playing in the clear water. We-hiked upstream, against little rapids. Suddenly we heard a roaring sound, and as we came around a bend, we saw what was causing it.
A huge waterfall! It rose high above us. “Wow!” I said. “Let’s climb it!” “No way,” said Dad. “End of the road.” We turned back but I couldn’t stop thinking about the waterfall and how much I’d like to climb it. Later, lying in my bag, I thought of the waterfall, wondering what was on the top... then finally I fell asleep.
The sun was hot as a bonfire. We cut leaves as wide as elephants’ ears, and tied them on our heads to keep us cool. Then we waded against the little rapids deep into the stream. I was the first one to the waterfall. “Let’s go up. I think there must be something unique out there,” I said. My brother smiled. “If you go, I will,” he said.
I found a way alongside the falls, and then we climbed like mountain goats. Mom shouted, “Be careful!” And we inched our way up and up—the tips of our toes gripping thin ledges (岩石突出部分), our fingers finding cracks. Sometimes rocks were unstable, but we clung (粘住) like glue. We had to.
The waterfall roared by our ears. “I’m scared,” said my brother. I said, “Just don’t look down.” Near the top, a tree grew out of the rock. It was just what we needed. When we stood at the top, we clapped our hands and shouted down, “Hey Mom, Dad! It’s like a whole other world up here! Come on up! You can do it!” And I did a little dance.
