San Bruno and Cortland Ave., 1915, looking north with Bernal Heights rising to the immediate left and Potrero Hill in the distance. Islais Creek wetlands occupy today's Bayshore Blvd. industrial zone. These wetlands also drained Precita Creek, which ran down beneath Army Street on the north side of Bernal Heights. The old H streetcar is visible running along San Bruno Avenue just east of Bernal Hill, just west and above the still un-"developed" wetlands of Islais Creek.

1997 Eastern view from Cortland Avenue over today's industrial zone in the former wetlands. The double-decker freeway in the distance is I-280, which predictably suffered structural damage in the 1989 earthquake due to its construction on former bay mudflats.
