On October 5th my family and I went to Craters of the Moon National Monument and Preserve in Arco, Idaho. According to the National Park Service, this “weird and scenic landscape” is a vast ocean of lava flows with scattered islands of cinder cones and sagebrush.
When we arrived, we watched a movie about a part-time explorer named Robert Limbert who journeyed through the lava three times in the 1920s. His work helped the area become a national monument in 1924.
We attended a program by a ranger who taught us about the different types of lava called ‘a’a (pronounced “ah ah” – Hawaiian), which is sharp loose rock, and pahoehoe (pronounced “pa hoy hoy” – Hawaiian), which is wrinkly and smooth rock. The ranger also told us about the vegetation that grows there like Limber Pine, and animals that survive there like Pikas.
After a bit, the ranger brought us to the caves where we went around touring it. We saw mini pointed rocks hanging from the ceiling; the cave was really dark but it was still fun. It was hard to climb over the collapses and the big rocks in the caves. The cave was called Indian tunnel. Then when we got out, we explored a few other caves called Honeydew, Boy-scout and Beauty cave.
