The Serpens North Cluster is a nearby low mass star forming region which is part of the Gould Belt. It contains a range of young stars thought to correspond to two different bursts of star formation and so provides the opportunity to study different stages of cluster formation. Here we present recent results based on a detailed analysis of molecular line and dust continuum data of this region. By studying the dynamics, column density and dust temperature structure of Serpens we propose that a cloud-cloud collision has been responsible for the trigger of the most recent episode of star formation. This scenario has been explored using SPH simulations. These simulations are able to successfully explain the similarities and differences observed in the two sub-protoclusters composing Serpens North.
