We have mapped the Auriga/California molecular cloud with the Herschel PACSand SPIRE cameras and the Bolocam 1.1 mm camera on the Caltech SubmillimeterObservatory (CSO) with the eventual goal of quantifying the star formation andcloud structure in this Giant Molecular Cloud (GMC) that is comparable in sizeand mass to the Orion GMC, but which appears to be forming far fewer stars. Wehave tabulated 60 compact 70/160um sources that are likely pre-main-sequenceobjects and correlated those with Spitzer and WISE mid-IR sources. At 1.1 mm wefind 18 cold, compact sources and discuss their properties. The most importantresult from this part of our study is that we find a modest number ofadditional compact young objects beyond those identified at shorter wavelengthswith Spitzer. We also describe the dust column density and temperaturestructure derived from our photometric maps. The column density peaks at a fewx 10^22 cm^-2 (N_H2) and is distributed in a clear filamentary structure alongwhich nearly all the pre-main-sequence objects are found. We compare the YSOsurface density to the gas column density and find a strong non-linearcorrelation between them. The dust temperature in the densest parts of thefilaments drops to ~10K from values ~ 14--15K in the low density parts of thecloud. We also derive the cumulative mass fraction and probability densityfunction of material in the cloud which we compare with similar data on otherstar-forming clouds.
