Remnants of wilderness

"It is a city of ravines. Remnants of wilderness have been left behind. Through these great sunken gardens you can traverse the city beneath the streets, look up to the floating neighbourhoods, houses built in the treetops. ... Forgotten rivers, abandoned quarries, the remains of an Iroquois fortress. Public parks hazy with subtropical memory, a city built in the bowl of a prehistoric lake." Fugitive Pieces Ann Michaels (1996)
