I remember reading about the building of Dodger Stadium in Chavez Ravine. In my youthful imagination, there was a deep, long crack in the earth in which a baseball stadium had been pushed. Perhaps you could step from the edge of the ravine right into the top level of seating. Looking at an aerial photograph of Los Angeles, which Chavez Ravine supposedly at center, I see nothing that looks like my idea of a ravine, a walled channel of some kind, something like a canyon, perhaps, but not as big. What’s my malfunction here? Do I have a mistaken idea of what a ravine is? Where is the ravine?
A ravine makes for a very bumpy parking lot. Most of the depressions in the area were filled in when the stadium was built and the land leveled. See this photo. And this one. Now look at the stadium today.
I always felt like I was on the edge of a damned ravine if we were sitting up top! 
Player seats are much better…
ETA- in all seriousness, remember that there were quite a few people living in Chavez Ravine. So it wasn’t a steep-sided ravine in the classic sense.
I can’t recall the name of it, but there was a comic book character back in the early sixties called Chavez Ravine. He was a stereotypical Mexican bandito.
Lving in LA, I got the joke, but wondered at the time whether anyone living out of So Cal would understand it.
Having grown up and lived half way up a very steep hill just a couple of miles north of Chavez Ravine, I can assure that people will build houses damn near anywhere. Even on the sides of steep ravines.
