Information

This site provides another great example where tuffs were baked by lava. In this case, note that the ash/tuff layer is sandwiched between two basalt flows, and it has been baked red on both sides. Also, observe the extreme tilting of the rocks here. Knowing the layers have been tilted down to the east, can you identify which side was originally up?
