OB associations are ideal sites for probing the formation of low mass stars. There has been little systematic study of the low mass stars in the largest nearby OB association, Orion OB1, aside from the Orion Nebula and σ Ori clusters. In an attempt to map the mass function and its spatial variation from 40 to below 0.01 M_&sun;, we have completed a near-IR (JHK) survey of about 18 square degrees in the Orion OB1a and OB1b associations using the CPAPIR camera on the SMARTS/CTIO 1.5m telescope, supplemented by a VRI survey using the Steward Observatory Bok/90Prime and the KPNO 4m/MOSAIC cameras, as well as deep 4m/NEWFIRM images. The photometry reveals thousands of candidate association members. We request time with HYDRA to obtain spectra of the brighter candidate members (V<19), in order to confirm youth and membership from Li abundances, chromospheric activity, and radial velocities.
