steeper slopes have many line parallel, bunched together
The peaks we use are as follows: (Pu'u is the Hawaiian word for peak)
Pu'u Ha
Pu'u La'e La'e
Pu'u Hoku ula
The mountains we will use are some of the five major volcanoes on our island:
Mauna Kea ("white mountain")
Mauna Loa ("long mountain")
Hualalai
Kohala
Kilauea
Questions:
on a contour map, if parallel lines are close together, what feature is this?
you see V shaped lines moving from a peak to lower altitude, what is this?
same question, only backwards, inverted V
what do peaks look like on a contour map?
Finding yourself on the map:
hold your pencil on the peak you have sighted
calculate the degrees the peak would see you: if less than 180°, then add 180°, if more than 180, subtract 180.
from the peak set your compass on the peak and rotate until the degrees from north (vertical lines on the map) align with your number
draw a line backwards from that point
where at least three lines intersect, this is where you are
Finding a lost person:
You are injured in the rain forest, and have only a little battery left on your phone. Your GPS is not working since the rain forest blocks the signal, but you can see three peaks, and you can call 911, but only briefly.
Measure the compass heading to each peak, and tell the 911 folks where you are.
Help should come soon!
Below are photos of the information 911 received. Your job is to find your lost classmates:
