From Halopedia, the Halo wiki
The Utgard Memorial Hospital was a hospital in Utgard on the planet Harvest. It was in this hospital that Staff Sergeant Avery Johnson was placed after his fight with Covenant Kig-Yar aboard Minor Transgression. He was then debriefed with Governor Nils Thune and Lieutenant Commander Jilan al-Cygni about humanity's first contact with extra-terrestrial life. The Utgard Memorial Hospital was likely destroyed when Harvest was glassed.
