The evolution and origin of the residual ice caps and the layered deposits are poorly understood. The layered deposits are thought to be a record of the climatic variations on Mars, which are possibly due to variations in the planet's orbit. Just like the core samples from the Antarctic, they can help us to look in to the past climate of Mars. We have developed a time dependent ice sublimation model to reproduce the observed shape of the North Polar Ice Cap. Results of the model were compared to the MOLA topographic profiles. We attempted to constrain the time scale of the formation of the current ice caps, having sublimation as the only process that modulates the shape of the ice caps. Spiraling troughs in the polar layered deposits are a long-standing mystery. Their formation has not been yet explained. We attempted to analyze trough shapes and their time scales with the sublimation model. The model can reproduce the shape of the troughs very well. Sublimation models can not fully explain the process of the trough formation. However, the model can help to bound the time scales for trough formation. We argued that sublimation is a very important process for the evolution of the ice caps and its time scales are shorter than that of the ice flow. In this work we will present comparison of the sublimation model results for the North and South Polar Ice caps and analysis of the trough shapes for both poles. Additional information is contained in the original extended abstract.
