Geocache Description:


Experience this EarthCache

Welcome to downtown Cincinnati! Fountain Square is one of the most iconic locations in Cincinnati and is home to the Tyler Davidson Fountain.

We have brought you here to have a look at the variety of stones used to construct this plaza, which look very different from the local grey limestone bedrock (which is a sedimentary rock). To answer the questions below, examine the rocks that make up the fountain and the paving stones around the square. Finally, look up at the fountain itself to answer the final passport question.

All of these rocks are igneous rocks that originate in very different places! Igneous rocks form when magma cools and crystallizes. Even though the rocks was used in constructing Fountain Square are all igneous, they may look very different from one another because of their chemical composition. Did you know: Not all magma comes from volcanoes.
