We present the JCMT Gould Belt Survey's first look results of the southern extent of the Orion A Molecular Cloud ({delta}3.7x10^21^cm^-2^). The remaining 28 per cent of these objects, which are expected to be embedded in dust and gas, may be misclassified. Finally, we suggest that there is an evolution in the velocity dispersion of YSOs such that sources which are more evolved are associated with higher velocities.
