An informal classification is a description that conveys a general or specific impression of a trap. For example, East Anschutz Ranch field, shown in the map and [[cross section]] in [[:file:classification-of-exploration-traps_fig2-1.png|Figure 1]], could be informally classified as an anticlinal trap. This informal classification conveys a very general impression of the trap. Informal classification can also be more specific. For example, we might classify East Anschutz as an elongated asymmetric anticline with a gently dipping back limb and a steeply to overturned forelimb.
