How to Track Down a Human: A Guide to Sign Cutting and Tracking Sign
WHAT IS SIGN
CUTTING
Sign cutting is a valuable and practical skill in survival situations. In many areas, the only way to find someone is by tracking their sign.
The process of detecting sign is known as “sign cutting.”
Sign cutting and tracking are two distinct and separate functions. Understanding the difference between them is critical.
- Sign cutting is the act
of detecting tracks or evidence of passage.
- Tracking is the act of
following sign.
Low Sign
|
High Sign
|
Tracks or partial tracks of humans, animals, or vehicles.

- Identify sign patterns
(types of sign are boot, dress shoe, cross trainer, etc.).
- Determine approximate
age of sign.
- Communicate sign cutting
activities to other individuals.
- Identify routes of
travel
HOW TO CUT SIGN
Everyone has the potential ability to detect and follow sign; but, as with any other skill, you must practice and gain experience to become proficient. Successful signcutting depends on:
- Awareness (seeing,
hearing, and sensing).
- Attention to detail.
- Self-developed
knowledge.
- Persistence.
- Knowledge of human
capabilities.
- Begin in areas that show
sign the best (soft dirt, fences, arroyos, sand, mud, snow, etc.).
- Be familiar with
potential routes in your area. Individuals generally walk along railroads,
power lines, roadways, gas lines, natural trails, fence lines, or towards
prominent distant landmarks.
- Be aware that while
traveling at night, individuals use beacons, lighted transmitter towers,
and highway noise as guides.
- Being able to establish
a route of travel will enable your partners to check lay-ups further up
ahead.
- Signcut with shadows
behind you.
- Change positions from
side to side as the sun changes.
- Detect sign by looking
ahead 20 to 30 feet for different colors or shades within the dirt.
- Hold a flashlight beam
low and shine it 10 to 15 feet ahead.
- Use the low beams of a
vehicle’s headlights. (Too much light floods the sign and makes it much
more difficult to follow.)
- Look for certain
patterns of shadows
- Time of Travel
(Day/Night)
- Characteristics of individuals
in the group (For example, children within the groups)
- Age of the sign
- Approximate number of individuals
- Direction of travel
Experienced signcutters can also
determine the characteristics of the people who left the tracks, including:
- Drop their heels hard,
leaving deeper indentations in the ground than those left when walking.
- Push the toes of their shoes
more deeply into the ground when they lift their feet. This also pushes
dirt backwards into the track.
- Have a much longer stride.
- A fresh walker makes a
steady stride mark. The heels are set down solidly, leaving a clean track.
The dirt from the toe is pushed lightly to the rear.
- A fatigued walker slides the
heel, leaving a “scuff” before the heel is set down. Dirt is pulled
forward out of the track, and the length of the stride is considerably
shortened.
Mental
condition is indicated by erratic or irregular patterns of travel. Sign showing
that a person is changing from a walk to a run, or is varying the direction of
travel, can indicate fright or confusion. Although mental condition is an
important factor to be noted, you should not overlook the fact that the person
they are tracking may be attempting to evade apprehension or may be lost
Physique
You
can compare the details of their own tracks with the details of the tracks they
are following. If you know your own weight and the length and width of your
footwear, your can estimate the size and weight of the person you are pursuing.
Keep in mind that signcutters can sometimes be fooled if an illegal alien is
carrying a load or a heavy object
Gender
- Tracks left by a woman have
a smaller width-to-length ratio than tracks left by a man.
- Shoes worn by women have
much smaller designs in the soles.
- Women tend to walk straight
footed or pigeon toed, while men tend to leave tracks that are turned out
and splay footed
You can determine approximate group size by identifying the
different types of sign within the tracks.
Here is a method to help you determine the size of the group you are
following: - Try to determine the average
stride of the group, based on the footprints that you see. Most people in
the group will walk with approximately the same stride so that they stay
together.
- Mark that distance off
(starting and ending mark).
- Count the number of
identifiable prints within that distance. Divide by two. This is the
approximate number of individuals in the group.
- If desired, repeat this
process a second or third time, and then take the average. This will
provide you with a more accurate estimate
If
a group suspects they are being followed, you will notice their sign/tracks
stop. The group may split up or backtrack
Tracks age differently depending on the climate and geographic area. It is easier to determine the age of tracks if you are aware of the weather conditions over the last few days, hours, and minutes:
Dew, Frost, and Fog make Signcutting Easier
As
the temperature reaches the dew point (the temperature at
which the air will no longer carry the humidity level), water beads up on top
of thick vegetation or grass, making tracking significantly easier. As dew
dries, it leaves ground slightly “fluffed up,” taking the shine away from a
track in varying degrees. Frost also makes tracking easier. Fog
has essentially the same effect on sign as dew, with heavier concentrations of moisture
on the top layer
Signcutting
after rain can make it easier to age tracks and accurately estimate time
elements. However, in areas of clay concentrations, the clay builds up on the
bottom of the foot, which makes sign very difficult to see. Heavy rain
obliterates tracks. This forces You to make educated guesses as to where to
look for sign that is likely to be “on top” of the rain
Temperature Affects the Appearance of Sign
Heat
dries out moisture (discoloration) in the track, accelerating the aging
process. Cold slows down the aging process by retaining the moisture. When
signcutting on frozen ground, You should look for small pebble displacement,
scuff marks, and broken twigs and branches
Wind Makes Signcutting Difficult
Strong,
persistent wind makes signcutting very difficult. Edges of the sign are the
first to go, leaving the center and a diminishing trail. The effects on the
aging process differ based on the speed and strength of the wind
Determining Age of Sign
Determining the age of sign is a skill learned through
practice. You should also consider the
abundance of animal life in the area when determining the age of sign.
- Tiny insects are
constantly moving and are likely to cross sign in most environments. This
is called "bug sign."
- Certain types of
animals are more likely to cross sign depending on the time of day and
their population in that area.
- The lack of animal
tracks in a certain area may also be a factor to be considered.
DISGUISING
YOUR SIGN
Walking Backwards
- Persons walking backwards
have a smaller stride.
- The toe imprint is deeper
than the heel imprint.
- It is impossible to walk
backwards accurately in one’s own tracks.
- A person walking backwards
is moving closer to the tracker.
- The person walking backwards
damages more vegetation and creates more sign than when walking forwards.
- Soft shoulders on either
side of the road facilitate signcutting.
- The person being tracked
will not stay on the road for long for fear of detection.
- The Agent and the person
being tracked can see for a long distance in either direction.
- It is easier to pick up a
reference sign from mud or soil transferred from boots or shoes to the
road surface.
- On a dirt road, track aging
can be performed if the tracker is aware of traffic flow in the area
- Toes scuffing the ground.
- Vegetation that has been
dragged along, not just kicked or stepped on.
- Hand imprints on the ground.
- Excessive noise produced by
the person being tracked
Suspects
may try to conceal sign by walking with their feet as close as possible to the
base of the brushes; or, if possible, in the base of the brushes. Brush hopping
and walking cause excessive flattening or deformation of the brushes,
especially if dry and brittle
Rock Walking
Rock walking
is very effective if enough large rocks are available. You should look for:
- Scuffmarks and scrapes on
rocks.
- Displaced, compressed rocks.
- Limited direction of
travel.
- Leapfrogging by the individuals
in the group by jumping ahead to the next wash, road, or soft area
- Decreasing amount of sign
or number of tracks.
- Sign leading away from the
main group.
Brushing Out or Covering Tracks
- An absence of animal signs
in the area (because they were brushed out).
- Discolored terrain and
leaves in the area.
- A different weathered look
than the surrounding area. Sign made to conceal sign. Brushing out is sign
in itself and recognition is easy if you know what you are looking for
- Silt flowing downstream.
- Tracks leading into and out
of the stream. (The suspect has to come out sometime.) The direction of
travel can be determined from the moisture trail left upon the suspect’s
departure.
- Algae removed from rocks in
the streambed by boots or shoes
Organization of Sign cutting Teams
Sign cutting operations are a team effort. Precise
descriptions of the sign are invaluable to other team members. Terms used to
identify individual types of sign are distinctive but may vary from station to
station. You should familiarize themselves with locally accepted terminology
and descriptions for types of footgear and their identifying patterns
To ensure that the oncoming shift will not follow
the same sign: - You should always mark
the sign trail being followed by drawing an “X” or initialing the trail in
the dirt.
- Sign cutting
information should be recorded and passed on by outgoing shifts, unless
the next shift has started before the information can be relayed.
- You may mark the soles
of their own footgear by cutting a notch or identifiable marking in the
heel; this helps identify previously worked sign.
- Recording GPS
coordinates helps identify trails and routes of travel and provides
valuable information to the oncoming shifts
As we mentioned earlier in this lesson, tracks and other
sign can best be seen by looking in the direction of the sun at an angle. The sign cutting route should be laid out so
that you are working into the sun as much as possible.
Each Agent makes an initial “cut” (checks his or her
assigned area for fresh sign). When sign is detected, a thorough, yet rapid, analysis of the sign is
made. You should check the entire cut for sign. Larger or more important
findings may be farther along in the cut, and will be missed if the Agent works
only the first set of tracks discovered.
After making cuts, each Agent in the tracking team summarizes his or her findings (group's size, track descriptions, known time elements, etc.) and communicates them to the team. The Team Leader then designates which set of tracks is to be worked first. Tracking is most productive and efficient when you work as a team.
If staffing permits, tracking in
pairs increases officer safety. One Agent can track the group using sign while
the other Agent keeps a lookout for potential hazards.
When working tracks: - The Initiating Agent
determines a line of travel.
- Team members cut for
sign in the group's most likely direction of travel.
- Leapfrogging is used
to make up time in order to catch up to the group.
- Forward you make
shorter and shorter cuts as sign cutting continues.
- The Agent on the sign
should begin to cut in expanding circles.
- Team members should
close in and focus on cutting in diminishing circles until the sign or
subjects are located, or a new line is established.
- Extra care and caution
should be exercised
- Individuals who are
walking typically have a destination in mind.
- Effective tracking
requires teamwork. Performing this alone requires more effort and safety
awareness.
- It is important to
have a reasonable idea of how much “lead time” the subjects being tracked
have. You can track all day, but if they cannot cut the sign faster than
the people they are tracking are making it, they will never catch them
In this section, we will focus on
basic tracking technique:
- Start early.
- Work into the sun.
- Check entire cut for
sign.
- Communicate with other
You.
- Work tracks.
Sign cutting shifts generally
start early so that you can be in their area by the time the sun comes up. Sign
cutting during dawn hours:
- Permits maximum
visibility of sign.
- Gains valuable time on
those aliens whose tracks are found.
