Resumen:
Evidence is presented indicating that the young star cluster Westerlund~2 lies $d_{odot}sim3.0$ kpc in the direction of Carina. The distance is tied partly to new $UBVRI_c$ photometry and revised spectral classifications for cluster stars, which imply that dust in the direction of Carina is characterized by an anomalous extinction law ($R_Vsim3.8$). That result was determined from a multi-faceted approach relying on the variable-extinction and color excess methods.
