CONTINENTAL GLACIER
LAB EXERCISE

 

You have until the end of April 5th to complete this lab assignment.

This is a cartography assignment worth 15 points. Cartography is the study of maps and map-making. Open up each of the six maps below. Enlarge the maps as needed.

14,800 Years Before Present

14,000 Years Before Present

13,800 Years Before Present

12,500 Years Before Present

11,000 Years Before Present

9,500 Years Before Present

I want you to become familiar with how the glacier retreated out of Michigan from 14,800 years ago to 9,500 years ago. The maps above show the sequence of glacial retreat.

In order to help you become familiar with this process, please draw in the glacial boundary along with any pro-glacial lakes (shown in blue) on the blank maps provided below. I don't expect you to memorize the maps above, but I need to know that you have studied the maps and have become familiar with the process of retreat.

You have some options here. I am providing blank maps for you in three different formats (PDF, JPEG and MS-Word). You can use any method of drawing on these blank maps as long as it is easy to open on my end.

JPEG Images - PDF Images - MS Word Images

Option A - I know that many of you can draw on the images received on your phone. Perhaps you could utilize the JPEG images above to make that happen.

Option B - If you would rather print out each page on paper using PDF or MS-Word and then draw in the boundaries with a pencil or marker, you could do that, take a picture of the final drawings and send it to me. If you choose this option, please line up all drawings and take just one photo and send it.

Option C - If you have access to a simple drawing tool on your computer, you can open up the blank JPEG maps and draw in the glacial boundaries and pro-glacial lakes (save and send).

Option D - any reasonable idea that is not listed here. Maybe you know of an online drawing tool for kids that is easy to use. We don't need anything real fancy. No need to run it by me if you know that it will work and you know that I can receive it easily via e-mail.

INSTRUCTIONS

1. Draw in a line showing the position of the glacial snout (in relation to today's Great Lakes). Be as accurate as you can. Use a color that is easy to see (not black). Don't place any letters or numbers on the map (the maps online have letters and numbers-- not our concern right now).

2. Draw in any pro-glacial lakes as they appear on the maps (shown in blue). The first two maps will not have any lakes. Shade in the lakes so that it is absolutely clear where the lakes were located.
