</div>Almost half a century after the prediction and discovery of the $\Omega^-$ baryon, many properties of the $S=-2$ and $-3$ hyperon resonances remain unknown. In particular, quark-model predictions suggest there are many more Cascade states than have been seen in experiments. Recent theoretical modeling indicates photo-production to provide access to these states and their observables. The CLAS detector, part of JLAB's 6~GeV program, has provided a unique lens into photo-production of the lowest mass Cascade states at threshold, however the energy and luminosity reached was not sufficient to study the heavier $\Xi^*$'s or the $\Omega^-$. With the increased energy and better charged-kaon identification promised with CLAS12, we propose to study the production mechanisms of $S=-2, -3$ baryons with high precision and statistics in exclusive photo-nuclear reactions. <br>
