Site 1

Site 1 also known as Erebus is the largest of the three archaeological dig sites on Mars. It was discovered in 2115. It is made up of a series of chambers and underground tunnels covered in glyphs. Site 1 houses an ancient Martian portal, as well as the artifact. By the events of Doom 3, the UAC science teams on Mars were still working at Site 1.

Though alluded to in Dr. Pierce Rogers' video disk in Doom 3, Site 1 is never visited until the beginning of Resurrection of Evil. The first six levels of the game take place here.
