After we finished our plane table map, we packed up our camp and moved south to the area around Arrow Peak that is east of Pray, Montana
and set up our new campsite. We would be doing a geological map of the area around Arrow Peak. Each day we would go out on our own and
check out the outcrops. We would take the strike and dip of the beds. Dip is the angle the beds are at in respect to the horizon and
strike is the horizontal direction of the beds. We would identify the different formations and mark the location of where one formation
changed to another formation. We would map any faults we found. The eastern edge of the area consisted of igneous and metamorphic rocks,
so we would stop there. We were learning to map sedimentary formations and not intrusions. From all of the information we gathered, we
would be able to make a geological map. A geological map shows four dimensions which are length, width, height and time. We had a topographic map
of the area with us and use of aerial photos. I would collect samples of the rocks, mark the location on the map and record my findings
in a field notebook. We were mapping the Quadrant, Amsden, Mission Canyon, Lodgepole, Three Forks, Jefferson, Bighorn, Snowy Range,
Pilgrim, Park, Meagher and Wosely Formations.
I never was concerned about getting lost in the area. I had a map and compass, and knew how to use them. Even if I did get lost, all I
had to do was go downhill and follow the drainage pattern to get to a road in the area. The area was not that remote. If I had headed
east, I would have wound up in the Beartooth Mountain Range area. However, there was a main north-south road on that side of the area.
There were many things that I found and did while hiking around the area. One day I came across a dead fawn that had died from natural causes.
I found a small spring another day when I was running low on water. In those days, you could drink the water from the streams without
having to worry about it being contaminated. Sometimes I would find evidence that prospectors had been in the area. Time went fast and
we finally had to halt our mapping. We packed up the camp and went to a cabin owned by a friend of Dr. McMannis to spend a few days completing
our map and writing our report. We were allowed to take the information home and type it up formally to send back to Dr. McMannis for
our grade for the course.
After returning to Bozeman, I headed back home to Tacoma. On my way I stopped at Lewis and Clark Caverns for a tour through the limestone
caverns. We rode a short railroad from the parking lot to the base of the cliff where the caverns were located. Then we rode a cog railroad
up the cliff to the mouth of the caverns. From there, I drove to Missoula and stopped to look at the campus for the University of Montana. I
was planning on going there for graduate school. I then drove south and took the highway over Lolo Pass on the border between Idaho and
Montana. I followed the Clearwater River to Moscow, Idaho. I spent the night there with a schoolmate. Then I drove back across Washington
