Instructions
This tutorial starts with questions about the information displayed in the geovisualization, ranging
from geological units to the sorts of geographical coordinates, elevation and distance information
displayed in the data boxes in the upper left. The idea of this first sequence of questions is to make
you more familiar with the information at your disposal in the geovisualization. The tutorial also has mixed in a series of helicopter flights where to help you orient yourself to
this amazing mixture of topography and geology.
The questions should be quite easy. The idea is a tutorial and an orientation, and you get 7
tries to earn 100%. So relax, learn and enjoy.

In the Fast Travel menu, travel to 35.9713. -112.3166. What are the X-Y coordinates in meters from
the southwest corner? [X being meters east of the origin and & being meters north of the origin]
You are welcome to try to walk the avatar to the far southwestern corner (you cannot walk off the
edge of this world). QUESTION: In Fast Travel enter latitude 36.1259 and longitude -112.1174 and go to this
location. Write down the X coordinate that the avatar is standing on. You can see the
coordinates underneath the elevation.
You will be using "Fast Travel" a lot if you want to do the lab quickly. First - you open the menu using the arrow on the left side of the geoviz.
Second - you click on Fast Travel
Third - you enter the coordinates Fourth - click on the fast travel paper airplane icon and go
WARNING: There is a giant pool of questions and answers ... literally hundreds of questions in
the pool. We are doing this giant pool in order to encourage students to actually go through this
tutorial. In our experience, we know that students who skip the tutorial ... end up spending a lot more
time being frustrated than those who go through all of these questions.

Question 3
1 / 1 pts
Correct!
X: 30645, Y: 30735, hypotenuse 43402 m
X: 2991, Y: 57722, hypotenuse: 12582 m
Question 4
0.5 / 0.5 pts
Correct!
Landsat satellite data that approximates the visual image someone would see from orbit
Landsat satellite data displays the geologic layers
Now Fast Travel back to the starting point of the game (36.2000 -112.0350), and what are the X-Y
coordinates and how many meters is this from the southwest corner? (remember, the X-Y
coordinates for the southwest corner are 0,0) You get to use a formula you probably learned in middle
school, the formulae for the hypotenuse of a triangle. You
are welcome to use any website you want, such as simply
searching google (which pops up with solving for the
hypotenuse) such as this one:
https://www.omnicalculator.com/math/hypotenuse
(https://www.omnicalculator.com/math/hypotenuse) You just enter the Y coordinate as one variable and the X
coordinate as the other variable) and the online calculator
will solve for the distance in meters from the southwest
corner to the starting point for the game in meters. We are not torturing you with a reminder of middle school without reason! You will need to calculate
distances later in this lab, and so we just wanted you to know how easy this is. Just enter (the length
of X, same as a) and 30720 (the length of Y, same as b). The hypotenuse calculator will solve for C, the length of the hypotenuse, or the real distance in
meters from the origin (southwest corner) to the location in the game.
Examine the three slide bars on the lower right in the geovisualization. Try sliding the Landsat bar to
the right at 100%, with geology and triplanar at zero. Then push apply. What data are displayed?

Now, shift the geology bar to 100, with Landsat and Triplanar at zero. What data are being
displayed? Note: The triplanar layer is for aesthetics. You can shift the bars to whatever combination you like the
best. Our focused group liked Geology 75, Triplanar 25 for understanding the topography-rock
connection. QUESTION: In Fast Travel enter latitude 36.0947 and longitude -112.0664 and go to this
location. Write down the color of the geological unit pixel that the avatar is standing on. What
is it? [Select the closest answer, even if you think the color description is slightly off.]

time being frustrated than those who go through all of these questions. The geology units in the Grand Canyon region
exist in five broad age categories. These are
the categories that are displayed in the geology
Map Key. If you click on all the buttons, you'll
see all of the geological units displayed in the
key
If the Map Key annoys you, it is very easy to
remove it. Just click on the arrow (left side) to
open up the menu, then map, and then
identify. Surficial
- being materials like river sediment and landslide deposits that are geologically recent
(last million years or so). They are not really something you will see in this lab. They are too small for
the most part. Proterozoic (
Neo
proterozoic, Meso
proterozoic, Paleo
proterozoic) - these are extremely old
(hundreds of millions to billions of years old) and complex rocks that are found down in the deepest
parts of the Grand Canyon - in the inner gorge (granite gorge). These very old rocks are underneath
everything, but you only see them down in the inner.

Neoproterozoic
Paleozoic
- these are the horizontal layers that dominate the Grand Canyon region. They are the
focus of this lab. The Paleozoic Era is the period of time from about 250 million years ago (The
Kaibab Limestone at the top is about 270 million years old) to about 540 million years ago (at the
bottom, the Tapeats Sandstone). These are the most important Paleozoic rock units you will see and come to understand in this lab:
Unfortunately, the colors displayed in the game (those employed by the U.S. Geological Survey) do
not match this graphic produced by the National Park Service (from a booklet used to train rangers). QUESTION: What geological era dominates the rocks you will see in the Grand Canyon?
