Field Trip

Yesterday, on Tuesday morning, all the brazilians students and the geology class went to Park Craters of the Moon. Bob Brock, the college counselor of the Community School, and the geology teacher, Hannes, guide us for that whole morning. The park is a place where two thousands years ago had happened some eruptions. The landscape was amazing, it seemed to be an endless ocean of rocks. It was a opportunity to learn about the differences among the most kind of the vulcano rocks. Then we could analyze if they had more Bazaltic, or If they were a pahoehoe, or ah-ah.

We also entered in two caves, which are lava tubes - tunnels that once had been some "lava rivers". At the caves we could observe the layers where the lava had been years and years ago.
The first one were easier to pass through. because it was big and large, and was called the Indian Tunnel because there were some evidences that indian tribes lived there. It was a shelter for that tribes. The second one was more difficult to get in, it is named Boy Scout. In this one, the rocks were closed and it made the passages more tight and there was also ice on the rocks. When we arrived at the end of the second cave, all of us turned off ours lights and stayed almost 3 minutes in completely silence. It was really peaceful!
After we came out to the cave, we sang Happy Birthday to Joao!!!

Here are some pictures of these field trip...

As you can see a lot of ice in the ceiling

A stop for the Lunch Time

When we were going back to the school, we stopped besides the road to see a hot spring - a kind of lake or river made of warm water that comes from the underground layer.
