The concept of strike and dip is integral to field studies in geology, but can be challenging and frustrating for students to learn. A simple and inexpensive field tool has proven effective in helping students understand the relationship between the strike and dip of planar geologic structures. This tool can also illustrate the relationship between true dip and apparent dip, and serve as an aide to field measurements of linear structures. The use of this tool with a transit compass can help students make the transition from a conceptual understanding to the actual measurement and collection of structural data.
