What the snow shows

Four prints. Before you ask “who was it?”, ask: which way was it heading, and in what order were the tracks made?

Diagram of four prints in the snow Illustrative drawing, not a photograph. Two smaller prints, numbers 1 and 2, lie at the back of the group; two larger ones, numbers 3 and 4, lie in front of them. A direction arrow runs alongside: at first it is a question, and once all four contacts have been read it points from the small prints towards the large ones, as a hypothesis. Nominal scale: the bar corresponds to 10 cm in the drawing’s assumption. 1 2 3 4 ? 10 cm — nominal scaleIllustrative diagram · not a measurement
Illustrative diagram of four prints in the snow. A detailed description of the contacts is in the text below, in the section “The order of contacts”.

The order of contacts, written out

The same as in the drawing, without the drawing. The numbers are an assumption of the diagram: they cannot be seen in the field — the order has to be inferred from the shape and arrangement of the tracks.

  1. First front paw

    A small, rounded track at the back of the group. On its own it does not say which way the animal was going — it is only the first point of the sequence.

  2. Second front paw

    In this pattern the front paws land one after the other, so their tracks are offset along the line of movement. The second small track lies further from the start of the group than the first.

  3. First hind paw

    The hind paws are larger and in this pattern land ahead of the tracks of the front paws. A large track in front of small ones is one of the clues to direction.

  4. Second hind paw

    Both hind paws land almost simultaneously, so the order of 3 and 4 in the diagram is nominal. Only the whole group allows a direction to be proposed.

Proposed direction (hypothesis): from the small tracks towards the large ones. This is an inference from the arrangement of the group, not an observation of movement.

What the diagram does not settle: the species. A pattern like this — two smaller tracks at the back, two larger ones in front of them — is left by hares, among others, but also by other animals that move in bounds (to be confirmed by a specialist). Speed, length of bound and the size of the animal cannot be derived from the drawing.

The same print, less and less data

One print in three states of the snow. This is an illustrative drawing: it is not a reconstruction of any real track and does not indicate a species. Hatching means no data — not zero, and not a verdict.

1 · Compact snow (diagram)

Outline
legible
Toes
visible, separated
Claws
visible
Direction and rhythm
not recorded in a single print

Many features to compare — still only a hypothesis.

2 · Softened edges

Outline
partial
Toes
barely separated
Claws
no data
Direction and rhythm
not recorded in a single print

Fewer features — the hypothesis weakens.

3 · Thaw: a blurred hollow

Outline
widened, unreadable
Toes
no data
Claws
no data
Direction and rhythm
no data

Insufficient data. Neither the species nor the direction can be derived from this hollow — and that is a valid result.

The document that is not here

The photograph that is meant to stand here must have:

  • a scale or an object of known size in the frame,
  • the date and a verbal description of the snow (powdery, wet, frozen),
  • a second, wider shot showing the whole line of steps,
  • a general description of the place — without the exact location, especially for protected animals.

This draft has no such material, so it is neither drawn nor reconstructed as a “photograph”.

Version V2 showed a photograph of a roe deer track from Wikimedia Commons (authorship and licence were given according to the file description). It is a hoof print, not an example of a thaw, and no scale is visible in it — which is why it is not included in this draft. File page for re-verification.

Field sheet — the second layer

One sheet of paper instead of a notebook. Nothing is saved in the browser; print it or copy it out. Observe from roads and trails, and do not disturb the animals.

  • Date and time:
  • Area (in general terms, without coordinates; do not give the location of tracks of protected animals):
  • Snow, in words (powdery, wet, frozen…):
  • Object of known size in the frame (ruler, matchbox):
  • How many prints in the group and which are larger:
  • Photographs: print from above with a scale ☐ · whole line of steps ☐
  • Conclusion: ☐ direction (hypothesis): ………… ☐ insufficient data

Limits and sources

To be confirmed by a specialist: the biomechanics of the sequence, the limits of species identification. The numerical values from V2 (bound distances, percentages of print widening, route length) have not been carried over, because they were not checked against sources.

The sources from V2 remain as pointers for further verification. They were not opened in this pass, so no sentence on this page rests on them as a citation.
