Dark Matter Halos: Shapes, The Substructure Crisis, and Indirect   Detection
  In this proceeding, we briefly review three recent results. First, we show that halos formed in simulations with gas cooling are significantly rounder than halos formed in dissipationless $N$-body simulations. The increase in principle axis ratios is $\delta (c/a) ~ 0.2 - 0.4$ in the inner halo and remains significant at large radii. Second, we discuss the CDM substructure crisis and demonstrate the sensitivity of the crisis to the spectrum of primordial density fluctuations on small scales. Third, we assess the ability of experiments like VERITAS and GLAST to detect $\gamma$-rays from neutralino dark matter annihilation in dark subhalos about the MW.
