Extinction map of B59 in grayscale and contours (Román-Zúñiga et al. 2009), showing the known young stellar objects (YSOs) in the region (from Brooke et al. 2007; Forbrich et al. 2009), except for the Class III objects. Contours range from an A_v of 5 to 20 in steps of 5, and then by steps of 20. Note that there are only four known Class 0 and I protostars in the region. The black labels show designations of regions within B59 as adopted throughout the paper. Some cavities are indicated with grey arrows and labels, and are discussed further in the text.
