We exploit Spitzer/GLIMPSE and Spitzer/MIPSGAL Galactic Plane observations to study the star forming activity taking place in the Vulpecula region (l=59-61 b=-0.2) where nearby OB associations radiate a copious amount of ionizing photons powering bright HII regions. These PDRs are revealed in the near- and mid-IR by hot dust grain emission. Several "elephant trunk" or "pillar" structures are also present inside and in the vicinity of Sh2-86. We make use of recently released GLIMPSE and MIPSGAL Point Source Catalogs to identify and classify Young Stellar Objects in a 2x3 degree region centered on a couple of newly discovered pillars. The goal of this study is to get a reliable census of star formation history in the complex, and examine whether triggered star formation occurs at the interface of the cold molecular material and the energetic HII regions.
