Over several decades, the limit equilibrium method has dominated the usage over any other method for slope stability investigations. General two-dimensional limit equilibrium formulation was extended by development of a generalized model for three-dimensional analysis. Design of open pit slopes is becoming more and more important highways are being designed at perilous terrain. With the advancement in research numerous methods have been developed for slope stability analysis which discussed briefly in this paper. Uncertainty is a very crucial factor in slope design as an increase in one degree in cut slope might make a slope unstable and vice versa. Conventional slope practice is often based on factor of safety which can not explicitly address the uncertainty; this led to the development of probabilistic slope stability analysis. A case study from Deccan traps, in Mahabaleshwar, India has been studied using FLAC SLOPE 5.0, a finite difference code. Critical observations about the slope have been discussed in the paper
