Abstract
Embedded clusters are the fundamental units of star formation in our Galaxy, therefore studying their properties is critical for understanding how star formation proceeds on both the local and Galactic scale. We have surveyed embedded clusters in local molecular clouds with FLAMINGOS and are investigating the star forming histories, IMF, structure and evolution of these young clusters. In this presentation, I will discuss our results for the clusters in the Rosette and Orion star forming complexes where we find evidence for the evolution of cluster structure and variations in the low mass end of the initial mass function.
