Identifying Features on Kaiser Crater’s Floor
For this activity, you will analyze an image of Kaiser Crater’s floor. As you observe images, be sure to use the
Feature ID Charts to help you identify features.
Age
Describe How Feature Formed
Rank
Youngest
Feature Name
Oldest
Use this table to order the major (most noticeable) features according to their relative ages. The oldest feature
should be numbered 1, next oldest 2, 3, 4, 5, to the youngest number 6.

Example
1. Determine the scale factor for your
image:
a. Measure the distance across in
centimeters:
21 cm
b. Divide to figure out the scale of your
image:
c. 18 km = _21__ cm
d. 18 km / _21__ cm = 0.86 km/cm)
Scale Factor: 1cm = 0.86 km
2. Multiply the size of any feature
measured in centimeters by the scale
factor:
Example:
a. Width of channel = _2__ cm
b. _2__ cm X 0.86 km = _1.72_ km
c. Width of channel = 1.72 km
6
Objective – Students will be to reconstruct geologic events using empirical evidence.
Determine the scale factor for your image:
a. Measure the distance across in centimeters: _________cm.
b. Divide to figure out the scale of your image:
18 km =_______________ cm
18 km / cm = km/cm)
c. Scale Factor: 1cm = _______________km (Include this scale factor on your image).
**Remember, as you measure features on your image in centimeters, you will multiply that measurement
by your scale factor. Be sure to list the scale factor on your image as well as the sizes of features you
calculate.
Record the feature measurements into your Student Data Log sheet.
