To what extent do geology, wildlife and climate help create culture and a sense of place? Over the last few weeks I've had the chance to explore this question in four cities with very different climates: Los Angeles, San Francisco, Seattle and Vancouver.
In LA, the climate is hot and dry, with the city built within a bowl of mountains between the ocean on one side and desert on the other. Some places like Arizona and Texas embrace the desert as part of who they are, creating gardens of succulents like the Tequila cactus (which I'm told produces a sweet drinkable sap) and hardy arbuto trees with amazing bark which eventually strips off entirely and locust trees. These plants are in evidence on the hillsides next to the freeways, but hardly visible in the city at all. Instead, Los Angeles seems to be a city of dreams: green grass, palm trees and eucalyptus sustained only by sprinkler systems.
