Radio Source I in the Kleinmann-Low Nebula in Orion has recently been subject to intense scrutiny as the likely source of much of the luminosity and kinetic outflow energy in this massive-star-forming region. Two groups (Goddi et al. 2011 and Reid et al. 2007) have produced 7-mm radio continuum evidence for a disk. Furthermore, the inferred disk is perpendicular to an outflow seen most clearly in both maser and non-maser emission from the SiO molecule (e.g. Plambeck et al. 2009; Matthews et al. 2010). Using imaging with laser guide star adaptive optics on the Keck II Telescope, we have made the first detection of a infrared counterpart to the disk surrounding Source I, which is most prominently seen in a color image made with L' and Ms filters and is not present at K'. We interpret our data as the illuminated surface of a nearly edge-on disk of which only the northern surface is visible; the opposite, more distant surface lies behind the opaque disk. The collimated outflow oriented perpendicular to the disk may also be present in our L'/Ms color image. The infrared counterpart to Source I overlaps the nearby infrared feature IRc 2A, which we resolve into two peaks. This suggests that the distribution of interstellar gas surrounding the Source I disk is inhomogeneous; IRc 2A may consist of fortuitously placed cloud clumps that are illuminated and heated by Source I. We further present our preliminary analysis of the proper motions of sources I, n, IRc 2A, and IRc 2C, in which we explore whether IRc 2A and Source I share a common motion.
