The goal of Galactic Archeology is to reveal how galaxies are built by looking at the current visible evidence and inferring the past. This requires knowledge of some of the most difficult aspects of Astronomy: determining ages, distances for individual stars. Using the APOGEE survey and augmenting with the GAIA survey we are able to determine chemical composition, space velocities, distances and ages for hundreds of thousands of giant stars across all components of the Milky Way. I will focus on the APOGEE results for the halo and the disk and show how these spectra may reveal the origin stories for the Milky Way stellar components.
