GG303 Lab 3 9/6/11 1 Three Point Problems and Map Interpretation Exercise 1 (29 points total) Three points with the following coordinates lie on a planar bed: A: 100m N, 400m E, 400m elev; B: 0m N, 0m E, 200m elev; C: 300m N, 0m E, 500m elev. You are asked to find the orientation of the plane as in the example of 3.1. Round your answers to the nearest degree . 1a Plot and label the points on a separate piece of paper using a scale of 5 cm = 250 m. Put the origin in the center of the page, and draw the east-axis parallel to the long dimension of the page . (3) 1b Add a correctly dimensioned scale bar and a north arrow. (2) 1c Draw and label a line of strike (structure contour) through pt A for the bed (2) 1d Determine to the nearest 45° (i.e., N, NE, E, SE, S, SW, W, or NW) the direction of dip and write it here: direction of dip = _____________(1) 1e Measure the strike of the bed (use the right-hand rule) and write it here: strike = _______(2) 1f Draw a dashed cross section line (fold line) through point E (plot E at 0m N, -200m E) that
