We have found over 200 objects in the GLIMPSE survey that appear to be outflows. These objects show excess emission in the [4.5] micron band compared to the other IRAC bands ([3.6], [5.8], and [8.0]). They are extended typically on scales of 10 arcseconds. We obtained molecular hydrogen (2.122 micron) images with the WIYN Observatory on three of the sources. The excess molecular hydrogen in each of the objects provides further evidence that these are shocked outflows from young stellar objects. We measured the [24] micron flux for each source available from the MIPSGAL Survey. The [8.0]-[24] colors are generally greater than 5, indicating that these are very young sources. In this poster we show sample images of selected outflow regions from GLIMPSE, MIPSGAL and WIYN, and discuss the energetics of the three sources with the ancillary WIYN data.
