The Abelian Sandpile Model is a simple cellular automaton describing the dynamics of a pile of sand under particle addition. It presents Self-Organized Criticality and seems to display allometry. I will present a number of deterministic protocols where patches emerge, playing a crucial role in the description of the final configuration. I will then propose a classification of these patches by means of new, unidimensional, objects, the strings. The interplay of these two classes of object will be investigated.
