Directly imaging the suspension-air interface, we observe dilation beyond a critical strain $\\gamma_c$ and the end of shear thickening as the maximum confining stress is reached and the contact line moves. Analyzing the shear profile, we extract the viscosity contributions due to hydrodynamics $\\eta_\\mu$, dilation $\\eta_c$ and sedimentation $\\eta_g$. While $\\eta_g$ governs the shear thinning regime, $\\eta_\\mu$ and $\\eta_c$ together determine the shear thickening behavior.
