An ultralarge liquid argon time projection chamber based neutrino detector will have the uncommon ability to detect atmospheric nuτ/nu τ events. This paper discusses the most promising modes for identifying charged current nuτ/nu τ, and shows that, with simple kinematic cuts, ∼30 nuτ+nu τ interactions can be isolated in a 100 kt·yr exposure, with greater than 4sigma significance. This sample is sufficient to perform flux-averaged total cross-section and cross-section shape parametrization measurements—the first steps toward using nuτ/nu τ to search for physics beyond the standard model.
