Two high-Galactic latitude molecular clouds (HLC) in the region of IC 2118, the Witch Head Nebula, appear to be forming stars (Kun et al.\ 2004). Star formation in HLCs, while rare, may be the origin of some of the apparently isolated T~Tauri stars revealed by ROSAT. At only ~210 pc away, the clouds in IC 2118 are thought to be excited by Rigel. Kun et al.\ (2004) reported the discovery of several T~Tauri stars in this region and estimated their ages to be 2.5 Myr. We observed a ~5\prime\times15\prime region centered on the head of the northernmost cloud with Spitzer, using IRAC (3.6, 4.5, 5.8, and 8 microns) and MIPS (24, 70, and 160 microns). We have approximately quadrupled the number of known or suspected young objects in this region. In this poster, we will present color-color plots and SEDs of these stars, and we will compare the properties of these stars to those of other star-forming regions. These observations are part of the Spitzer Space Telescope Research Program for Teachers and Students, so these data are also being used for educational purposes; please see our companion educational poster by Weehler et al.
