"These images represent the erasure of incredible diversity and beauty from the collective memory of Angelenos. But they also hint at a possible future for the city, which is currently debating a river revitalization effort. Though the river will never again flow in its natural state, some habitat restoration may allow for the return of animals that have sought refuge elsewhere. Given the city’s history of putting development before preservation, it remains to be seen what direction revitalization will take. But if we can remember what was lost, then certainly we can imagine what might be again."
