The Milky Way as Seen from Apache Point
We present the results of the analysis of spectra and photometry for more than 14,000 stars which are part of the second public data release of the Sloan Digital Sky Survey. We discuss the inferred metallicities and distances, which suggest that the formation of the Galactic thick disk took place over a short period of time.
