Spitzer has collected a wealth of data on star-forming regions in its first two years. Here, we present archival imaging results from IRAC and MIPS of a recently discovered protostellar outflow in a nearby cloud whose symmetry and appearance in the different IRAC bands make it a textbook example of a classic bipolar flow. The cavity walls are most prominent in IRAC Band 1 (3.6 microns), while the jet bow shocks dominate in IRAC Band 2 (4.5 microns). Absorption of bright background emission highlights the appearance of the infall envelope especially well in IRAC Band 4 (8.0 microns). Prospects for inferring outflow physics from these data, including flow mechanical luminosity, the ratio of infall to outflow power, and the nature of precessing jets and disks will be presented. Spitzer images of several already well-known protostellar flows, identified from previous ground-based studies, will also be displayed.

Financial support for this work from the Brinson Visiting Scholars Program of the Adler Planetarium, Chicago, is gratefully acknowledged.
