Instructions: Based on the images of DC resistivity and gravity results, and on your understanding of how these images were obtained (and their strengths and limitations), build a quick summary based on the following three headings. Either use the lines on the page, or build a new document.

1. How are the models from the two surveys similar (the same information comes from both surveys)?
