Map Check for Geology 101

Does your topographic map qualify for this project?

Please answer the following questions to see if you have a usable topographic map for your project. If your map does not pass this checklist, you will need to find a different map or consult with your TA for other options in time for the next lab. (See also the Help Doc posted on Angel.)

1. Is your map a USGS Topographic Quadrangle? ______
2. Does your copy of the topographic map show a title, scale, and north arrow? _______
3. What is the fractional (ratio) scale of your map? _____________
4. The scale should be a maximum of 1:100,000 (1:24,000 is preferred, if available). If the scale is “zoomed out” more than 1:100,000, your map is NOT adequate for this project.
5. Did you save/print your map so that the scale is 100% (same as paper original)? _______
6. Do you have a citation of the map source in proper format? _______
7. Can you clearly see the contour lines and labeled index contours showing elevation? _______
8. What is the contour interval (and is it in feet or meters)? _______
9. Are lines, labels, words, and latitude and longitude numbers clearly legible? _______

Does your geologic map qualify for this project?

Please answer the following questions to see if you have a usable geologic map for your project. If your map does not pass this checklist, you will need to find a different map or get more information about your map in time for the next lab.

1. Does your geologic map have a title, scale, and north arrow? _______
2. Is it a geologic map of an entire state? _______ If yes, it is NOT adequate for this project.
3. What is the fractional (ratio) scale of your map? _____________
4. The scale should be a maximum of 1:100,000 (1:24,000 is preferred, if available). If the scale is “zoomed out” more than 1:100,000, your map is NOT adequate for this project.
5.  Did you save/print your map so that the scale is 100% (same as paper original)? _______
6.  Do you have a citation of the map source in proper format? _______
7. Can you clearly see at least three rock units with symbols, and do you have a key/explanation that gives meaning to all these symbols, in terms of rock types and ages? _______
8.  Does your map show any geologic structures – faults or folds? _______ (If no, ask your TA)

Faults or folds will appear as dark/thick lines on your map and the symbols should be shown in the key/explanation. If you need help, ask your TA.
