Homework #4: Cross Section of the Project Area                                                              Dr. Sanders
Due Tuesday, March 5, 2002

Construct a cross section of the project area using the well boring data provided by e-mail.  Each student should construct one cross section.

The materials you will need are in Room S-124.  There you will find gridded paper in a roll that is wrapped in an orange plastic sleeve.  In addition, you will find the TopoTool rulers to use in plotting latitude and longitude, as well as the Naperville Quadrangle topographic maps.

Half the class (you know who you are) will do a roughly east-west cross section that extends from up on the moraine through the well, across the river, and at least a short distance out onto the outwash plain. The other half (you know who you are, too) will do a roughly north-south cross section that begins north of the river, passes through the well, goes through the lake to the south, and then crosses the river again.

Make the cross sections run in jagged lines that extend from point to point, rather than trying to make a perfectly straight line.  Use a vertical exaggeration of 100x--in other words, your vertical scale should be 100 times your horizontal scale.  The horizontal scale should equal the scale on the topographic map.

Draw your cross section in pencil!  It is possible that changes will be needed, and if you work in pencil, you will be able to make changes easily.

Be sure to include the horizontal and vertical scales, show the position of each boring that you used to plot the cross section (label it with the 5-digit well ID number), label the rivers/lakes, and give the cross section a title.  Make sure your name is on it somewhere.  In addition, please provide a copy of the topographic map on which you have shown the line of the cross section.
