(Important: please see Geodude's tips...)


Overview of the project

 This section could introduce the reason you are doing the field trip or lab exercise. What features are you going to see and why, what are you going to observe or sample and why, how does the trip satisfy the learning objectives of the course (these are linked in your syllabus), etc. 

Overview: Physiography and Geology of the Seminary Hill Natural Area

<describes the physiographic area visited during the lab--> east valley wall of Chehalis River at Centralia (Fig. 1).  Possible sources of information include Kruckeberg’s Natural history of the Puget Sound country, the Washington Div. of Geology and Earth Resources (websearch). There are many sources in the Kirk Library.  [NOTE:  a good choice for Fig. 1 would be a map or maps (road map and geologic map?)


Description of Field Site or sites (this could be included in the above section)

Slope, age of trees, species, etc (Fig. 2?) 

If you go to multiple locations, then each one could be set off in this report with a separate header.

Description of field techniques 

Explain how, when, and where we cored trees and collected cores. Note what data was collected and what was the data?, etc


Description of Sample preparation

Describes sample preparation—all steps (Fig. 3.?) The samples were scanned on an Epson Expression 1680 scanner at 1600 pixels per inch resolution (both x and y directions) by instructor and student volunteers. This resolution was converted so that the scale of measurement in Image J was in hundreths of a millimeter (.0.01mm).



Measurement of Samples
