Tracking Questions from Readers


"When measuring stride length, do you go from the heel of one print to the heel or toe of the other print?"

I measure stride length from the toe of one print to the heel of the next. Using a stride stick, also called a tracking stick, I can mark the stride length I'm tracking and if I can't find the next sign easily, the arc that the stride stick makes from the toe of the previous track narrows down where to look for the next sign. My stride sticks are 1/2 inch oak dowels, 36 inches in length. You can make one in the field with any decently straight stick at least 18 inches in length.  You can mark measurements by making notches on the stick.


And what am I looking for? Any flattening, disturbance, regularity or color change.

Using a rubber band or a tight fitting rubber washer is a good way to mark the measurements on your stride stick.  With more rubber bands or washers, you can also measure and mark width in the ball of foot; heel width or length for broken heels or raised heels. Half inch rubber washers will last longer than rubber bands and are easier to move when changing measurements.

In the picture below it appears that I am measuring from heel to heel, but look for the black rubber washer on the stride stick. It is located at the top of the print in front of me (see arrow). The end of the stick now can create an arc so I know where the next stride should be.






It's six of one, half dozen of another if you measure heel to heel or toe to heel. I was taught, 30+ years ago, to measure from toe to heel so that's how I do it...........oh, and sorry for taking three paragraphs for a question that could have been answered in one sentence.




"Can you go into more detail about "Pressure releases" and why or how they are important to tracking?"

When an object such as a human foot or animal hoof hits the ground, it disturbs the ground. It may be so subtle as to be undetectable by the naked eye, but it can compress, or gouge, or leave a regularity such as pattern or a line not seen else where. Disturbed dirt and bruised vegetation can provide a color change to indicate passage.  This is the flattening, disturbance, color change or regularity I'm talking about.

As the foot or hoof pushes off to leave the ground, that release also impacts on the disturbance left behind,  much more so in softer ground than in rocky, hard ground. The weight, speed and angle of the foot or hoof leaving the ground also influences what that pressure release looks like, often providing a clue as to what the human or animal was doing.....increasing stride and therefore speed, jumping side ways, stopping abruptly, looking up, moving with a leg injury, and getting tired are some things you can often tell from reading a pressure release.

So to answer your question, reading pressure releases are not critical to being able to cut sign or track. It just gives you more insight to your target, it's condition and what it may be thinking or doing.  Just one of many factors to consider.
