Rafting the Grand Canyon
This is the ultimate experience for a keen geologist: Seven days of rafting through 300 million years of flat-lying sedimentary rocks of the Palaeozoic era and an intriguing record of Precambrian sedimentary and crystalline rocks. I doubt if there is a better way to get introduced to all kinds of rocks (sedimentary, magmatic and metamorphic) and geological processes. This is in particular true if you have a knowledgeable guide who lets you experience the pure joy of being in this nature’s wonder. If you ever get the chance, don’t miss it!
