A redshift histogram constructed from current spectroscopic observations of the SSA22 protocluster reveals two separate peaks at $z = 3.065$ (blue) and $z = 3.095$ (red). Based on these data, we report updated overdensity and mass calculations for the SSA22 protocluster. We find $\\delta_{b,gal}=4.8 \\pm 1.8$, $\\delta_{r,gal}=9.5 \\pm 2.0$ for the blue and red peaks, respectively, and $\\delta_{t,gal}=7.6\\pm 1.4$ for the entire region.
