We present a 3 mm spectral line and continuum survey of L1451 in the PerseusMolecular Cloud. These observations are from the CARMA Large Area StarFormation Survey (CLASSy), which also imaged Barnard 1, NGC 1333, Serpens Mainand Serpens South. L1451 is the survey region with the lowest level of starformation activity---it contains no confirmed protostars. HCO+, HCN, and N2H+(J=1-0) are all detected throughout the region, with HCO+ the most spatiallywidespread, and molecular emission seen toward 90% of the area above N(H_2)column densities of 1.9x10^21 cm^-2. HCO+ has the broadest velocity dispersion,near 0.3 km/s on average, compared to ~0.15 km/s for the other molecules, thusrepresenting a range from supersonic to subsonic gas motions. Our non-binarydendrogram analysis reveals that the dense gas traced by each molecule hassimilar hierarchical structure, and that gas surrounding the candidate firsthydrostatic core (FHSC), L1451-mm, and other previously detected single-dishcontinuum clumps have similar hierarchical structure; this suggests thatdifferent sub-regions of L1451 are fragmenting on the pathway to forming youngstars. We determined the three-dimensional morphology of the largest detectabledense gas structures to be relatively ellipsoidal compared to other CLASSyregions, which appeared more flattened at largest scales. A virial analysisshows the most centrally condensed dust structures are likely unstable againstcollapse. Additionally, we identify a new spherical, centrally condensed N2H+feature that could be a new FHSC candidate. The overall results suggest L1451is a young region starting to form its generation of stars within turbulent,hierarchical structures.
