We spent most of our day in Mortimer Island. We worked hard to get samples from a very special part of a rock outcrop. There were black squiggles in the rock. The black squiggles are glass that was formed when the meteor hit. When rocks rub together fast, they can heat up and melt, forming the glass that we saw in the rocks. Things that can cause rocks to rub together fast enough to melt like this are meteor impacts and earthquakes. One of the things the scientists hope to do when they are back in their laboratory is to use samples of this glass to determine how long ago the meteor hit.
