Switzer Canyon

[1][2] Switzer Canyon remains an oasis of natural vegetation between some of the city's most urban neighborhoods and is a prime example of San Diego county's unique canyon-laced topography.

The development of the area of East San Diego called the "Steiner, Klauber, Choate and Castle Addition", now known as City Heights, was facilitated by a railroad which began service in July 1888.

This causeway was constructed of landfill material that was transferred from Nile Street in North Park, and its poor soil conditions allowed few plants to grow.

[10][11] Between 2000 and 2005, the group installed information kiosks along the trails on the canyon floor, and the western slope of the 30th Street causeway was rehabilitated with native plants that mitigate storm erosion.

[13] It is also home to dusky-footed woodrats, rabbits, coyotes, and numerous indigenous plant species including yerba santa, black sage, and evening primrose.
