We present early results from an October 2007 HARP observing run at the JCMT. The primary goal of our project was to map an isolated intermediate-mass star-forming region known as L1340 in order to investigate the possible effects produced by these late B spectral types on further star formation in their natal environment. The 12CO J=3-2 data reveal intriguing structures in the cloud, including multiple shells and arcs associated with these intermediate-mass stars. A number of our (as yet unpublished) 850 micron SCUBA sources appear to be coincident with the southern-most edge of the largest shell, which encompasses a trio of B stars. We discuss our HARP results in the light of our previously acquired data (near-infrared, submillimeter, and multi-J CO data) and archival data from the literature.
