So,
how old do you think these tracks are? I
know, but how would you guess their age, if you came upon them?
Aging tracks is an art, because so
many variables, such as whether the track is made in mud, sand or snow, the wind,
the sun and the rain, all play a part in how fast a track decays.
Dirt and Mud...
In
the summer, unless you are at the beach, the tracks that you find will be in
the dirt and mud. So how long do they
last before they crumble back into dust?
That depends...
Weathering...
Tracks
are affected by the weather, the wind, rain or fresh snow will gradually cause the
features to collapse until no fine details are left2. When a foot displaces soft, moist soil to form
a track, the moisture of the dirt holds the edges of the track sharp and intact,
but as air and sunlight dry the edges of the track, small bits which were held
in place by the moisture, fall into the print. If these bits are just beginning to drop into the
track, then it is probably fresh. If the
edges of the track are dry and crusty, the tracks are probably at least an hour
old. Remember this is only an
approximation, as the weathering of tracks will vary with the terrain.
Rain, wind and water...
A
light rain may round out the edges of a track. A short heavy rain might leave “pockmarks”
in the tracks and a heavy rain might erase the tracks completely. Remember when, and how hard the last rain was,
to correctly age any tracks.
Wind
also affects tracks, by drying them and blowing litter, sticks, or leaves into
it. Be sure that the litter was blown
into the tracks, and not crushed into them when the tracks were made. Remember when and how hard the wind blew to
age a track.
A
trail of tracks leaving a stream may appear to be weathered by rain, because of
water dripping from wet fur or clothing, down onto the tracks. A wet trail of tracks that slowly fades into a
dry trail shows that it is fresh.
So, how old are these tracks?
The pictures above were taken on a shaded, muddy, dirt road, approximately 24 hours apart. It didn’t rain either day, there was very little breeze, and the temperature and humidity were much the same on both days3.
Notice
how the details of track on the left are noticeably clear and sharp.
The details of the track on the right, photographed again about 24 hours later, are faded and much less distinct and clear. Notice also, how the entire track is uniformly dry.
Practice, practice, practice...
The
best way to learn to age tracks that you find is to practice, practice, practice, and here
are some tips.
Tom Brown Jr. explained that
“A good wind may smooth out a depression
made in dry sand within 30 seconds”4.
T.A.L. Dozer noted, “Tracks with well-defined, sharp features always appear to be fresher than smooth tracks. Make animpression with your thumb in the ground alongside the track so that you can see how the soil behaves”.
Tom
Brown Jr. wrote, “Under most conditions, though, the peaks of a track — one
made in, say, medium-hard garden soil — will have deteriorated or rounded
somewhat after 24 hours. In another day,
the mark may have accumulated debris, leaves, or pockmarks from raindrops. Eventually, as the track crumbles and fills or
is covered by other prints, it will disappear completely”.
Tim MacWelch explained that spider webs can help you age tracks “...broken
webs mean that someone or something has come down that trail within the past
hour, maybe an hour and a half if it’s cool weather. If the web is partially rebuilt, something
broke it about two hours ago. If the web
is complete, nothing went through that spot within the past three hours”.
I hope that this helps you determine just how long ago the tracks that
you find in the wilderness were set down.
