2. Project Selection  We looked through the topics and discussed which one we all had an interest in.  When we got down to three we did our research and found which one had the most resources available.  After about a week of research we came to a consensus about our topic.

3. Topic of Study  Categorize lunar impact craters 30km(±4km) in diameter as either Primary or Secondary based upon crater depth, diameter, and regional surroundings

4. Background Info  Morphology  Primary vs. Secondary  Crater counting

5. Primary Data Gathering  Gathered crater information (Identity, Diameter, Longitude & Latitude)  Compiled and documented craters that ranged from 26 – 34 kilometers.  Made use of Google Earth’s Moon feature to collect pictures of all the craters registered.

6. Detailed Data gathering  Examined Crater Region for similar sized impact sites  Calculated a ratio between given Depth and Diameter  Looked for trends between separate sets of data  Predicted Crater type upon the look of the Impact region against the Depth-Diameter Ratio

7. Data Crater Name: Lambert Location: 25.80°N 21.00°W Depth/Diameter Ratio:.09 Depth: 2.7km Diameter: 30km Regional Appearance; Crater is surrounded by many miniscule craters, Crater appears to have a complex inner geography Link to full spreadsheet: http://bit.ly/dVJH7j

8. Data Spreadsheet

9. Conclusion  Currently our team lacks sufficient amounts of data to come to determine any sort of trend between the Depth/Diameter Ratio and the appearance of the crater region to determine the classification of the impact sites.

10. Future Studies  Continue to gather data concerning crater depth and diameter  Possibly expand set of data to include; Crater age, edge slope, and temperature  Build up a website to exhibit set of craters coupled with their related information
