INSTRUCTIONS FOR MEASURING CARIBOU

All measurements must be made with a 1/4-inch wide flexible steel tape to the nearest one-eighth of an inch. (Note: A flexible steel cable can be used to measure points and main beams only.) Enter fractional figures in eighths, without reduction. Official measurements cannot be taken until the antlers have air dried for at least 60 days after the animal was killed.

A. Tip to Tip Spread is measured between tips of main beams.

B. Greatest Spread is measured between perpendiculars at a right angle to the center line of the skull at widest part, whether across main beams or points.

C. Inside Spread of Main Beams is measured at a right angle to the center line of the skull at widest point between main beams. Enter this measurement again as the Spread Credit if it is less than or equal to the length of the longer antler; if greater, enter longer antler length for Spread Credit.

D. Number of Points on Each Antler: To be counted a point, a projection must be at least one-half inch long, with length exceeding width at one-half inch or more of length. Beam tip is counted as a point but not measured as a point. There are no "abnormal" points in caribou.

E. Length of Main Beam is measured from the center of the lowest outside edge of burr over the outer side to the most distant point of the main beam. The point of beginning is that point on the burr where the center line along the outer curve of the beam intersects the burr.

F-1-2-3. Length of Points are measured from nearest edge of beam over outer curve to tip. Lay the tape along the outer curve of the beam so that the top edge of the tape coincides with the top edge of the beam on both sides of point to determine the baseline for point measurement. Record point lengths in appropriate blanks.

F-4-5. Length of Points are measured from the tip of the point to the top of the beam, then at a right angle to the bottom edge of beam. The Second Longest Top Point cannot be a point branch of the Longest Top Point.

G-1. Width of Brow is measured in a straight line from top edge to lower edge, as illustrated, with measurement line at a right angle to main axis of brow.

G-2. Width of Top Palm is measured from midpoint of lower edge of main beam to midpoint of a dip between points, at widest part of palm. The line of measurement begins and ends at midpoints of palm edges, which gives credit for palm thickness.

H-1-2-3-4. Circumferences are taken as illustrated for measurements. If brow point is missing, take H-1 at smallest point between burr and bez point. If rear point is missing, take H-2 and H-3 measurements at smallest place between bez and first top point. Do not depress the tape into any dips of the palm or main beam.
