I am passingly familiar with the geography of the area (lived in the Bay Area for almost 3 years) and I watch the show, so I've recognized landmarks before etc.
Pretty much all the residential areas nearby would be downhill from the range. It's an area of foothills rising up to the mountains on the east side of the Bay. So if the cannonball bounced from the range to the residential area, it's going more or less downhill (probably another reason why it could go so far). But yeah - first impact is going to be a bounce -before- the first house gets nailed, then the cannonball goes through the house upwards, has time to get some air, comes down and bounces on the next house's roof which is downhill a bit further, then finally winds up in the SUV further downhill yet.
