We invite you to explore a few of these very special places with us. This site is a collaborative effort of the US Geological Survey and National Park Service. We are adding, updating, and expanding weekly. We aim to inform and entice virtual and future park visitors with a non-technical approach to geology. We hope that everyone from middle-school age and up will find something of interest.
Information is presented at a variety of technical levels.
All of our 'entry' pages including the first page of any topic, including field trip stops, is presented at the most basic level. If you're interested in more detail, simply work your way through each site and you'll find that our presentation becomes increasingly specialized and uses more technical language. We have also included lots of material specifically aimed at park interpreters and educators. Most scientific terms are highlighted as links. Clicking on the term will take you to our glossary or other page that explains the term or concept.
