  The Lambda Orionis Star Forming Region is a complex structure which includes
the Col 69 (Lambda Orionis) cluster and the B30 & B35 dark clouds. We have
collected deep optical photometry and spectroscopy in the central cluster of
the SFR (Col 69), and combined with 2MASS IR data, in order to derive the
Initial Mass Function of the cluster, in the range 50-0.02 M(sun). In addition,
we have studied the H(alpha) and lithium equivalent widths, and the
optical-infrared photometry, to derive an age (5+-2 Myr) for Col 69, and to
compare these properties to those of B30 & B35 members.
