The UEC campus map is an optional artifact in the dormitory's main office at the University of Eastern Colorado. Duck under the furniture barricade into the office and pick it up from the counter straight ahead.
A layout of the University of Eastern Colorado campus, the grounds Joel and Ellie are crossing to reach the science building where they hope to find the Fireflies.
Firefly's recorder
The Firefly's recorder is an automatic artifact in the university science building. Joel picks it up from a dead Firefly in a cutscene, so it cannot be missed, and you can play the whole message later from the Artifacts menu.
Free Radicals
Free Radicals, issue 7 of Savage Starlight, is on the rusty hood of a car up the hill behind you as The University begins.
Fungal X-rays
The Fungal X-rays are an optional artifact in the university science building. After you follow Ellie through the short tunnel, turn left and check the far table next to the window.
Griggs's Firefly Pendant
Griggs's Firefly pendant lies on a table in the last tent of a camp outside the science building, in the Go Big Horns section of The University. It belonged to Erik Griggs.
