GEOLOGY IN COLORS: USING SIMPLIFIED, COLORABLE GEOLOGIC MAPS AS A VISUAL AND INTERACTIVE TOOL TO DEMONSTRATE THE FUNDAMENTALS OF WHATEVER GEOLOGY CLASS YOU TEACH

Geologic maps form the bedrock of our discipline by virtue of illustrating the type, age, and distribution of the bedrock on our Earth. The detailed information they can include – from topography to locations of folds and faults to distribution of specific rock types – makes them an invaluable tool for academics and professionals alike. Yet it is precisely because of their complexity that they play a very limited role in most introductory classrooms as the volume of information is likely to overwhelm most beginning students. To make geologic maps inviting to newcomers, I have made a series of simplified geologic maps using Adobe Illustrator to trace simplified distributions of rock over more detailed, published maps. I focused on broad characteristics of rock type (plutonic, volcanic, sedimentary, metamorphic) and large units of geologic time (eons, eras, and periods). The end result is a series of black-and-white, easily printable worksheets for students to color as a take-home project or an in-class, instructor-led exercise. Coloring is a hands-on, sensory experience that invites relaxation and close attention. By coloring maps, students are encouraged to gradually explore the map's key features, contemplate the scale of space and time represented, and – ideally – incorporate new geologic learning into their own “mental map” of the world. Color along as I lead an interactive demonstration. Colored pencils will be provided. Examples of coloring maps will be available to take home and to share with your students.
