Look out for the following indicators:
• COLOUR – Unnatural colours or colour change. The difference in colourwill depend on the length of time since emplacement, often clearer 24-48hrs after emplacement.
• TRANSFERENCE – Soil, sand, foliage and other debris deposited inplaces where nature would not cause it to be.
• REGULARITY – Geometric shapes and strange angles which do notnaturally occur.
