Let's do some sample GPS/MagnaProbe measurement
analysis. If the following depths were recorded
on a long walk (these are actual numbers from one of our MagnaProbe lines), how does the terrain appear?
Find the average of the following snow depths for each of the terrain/vegetation types.
Make a bar graph comparing the snow depths.
What relationship do you see between the vegetation type and snow depth?

WHERE IS MRS. CHEUVRONT??? LET'S PLOT!!!
LATITUDE: 68.48202 degrees North
LONGITUDE: 155.75247 degrees West
The temperature has dropped. The mountains have proved that they lie within the Arctic. Morning was cold and brisk. Frost formed on my braids along with my eyelashes. A cold job lay ahead for Glen and I. We would perform a Class 1 Chemical sample in the middle of the Brooks Range Mountains. The remote placement of the sampling site is essential to determine if Arctic haze chemical components are being deposited in the snow. I wore my heaviest parka, my hat, and gave up my warm mittens for two layers of cold latex gloves. The tyvek suit was cumbersome putting on over the layers of clothes. The wind was gracious to us and quieted while we performed the four-hour meticulous job. Our work was finished and it was time to travel out of the Brooks Range. The mountains lead us on a path, a portal out of the mountains. The portal was aligned with steep rocks and sculpted snow. The mountains had granted us a safe journey; they allowed us to bear witness to their beauty. The mountains could be a place of ferocious winds and cold air. We had been blessed with good weather and safe traveling. We traveled out of the mountains and the North slope lay ahead. At the base of the Brooks Range lies a sacred place called the Mesa Site. The Mesa Site sits as a large rock which holds ancient secrets. Archaelogists have found remains from humans dating back to 13,000 years ago. One could imagine a time long ago where humans sat on the rock and looked for mastodons and bisons to be hunted for food. The climate and life was different in the Arctic at that time. Our life on our journey was about to change; Ivotuk would be our safe haven for the evening.
