I present a study of ages of field stars from a sample of the Sloan Digital Sky Survey. The results are consolidated with a set of globular clusters and show that this stellar sample is composed by one dominant population of 10-12 Gyr. This supports the Eggen's formation scenario, which claims that the inner halo of the Milky Way formed rapidly, probably during the collapse of the proto-Galactic cloud.
