I will not make the argument that Columbus's arrival in the New World was insignificant merely because he was an absolutely awful person or because he didn't actually discover anything (which he himself maintained, claiming until his death that he'd merely found a different route to Asia). But think about this before you dismiss -- before Columbus, avocado, bell peppers, blueberries, cashews, cassava root, chili peppers, chocolate, cocaine, gourds, maize, peanuts, pecans pineapples, pumpkins, squash, tobacco, tomatoes, and vanilla were all unknown in the Old World and alcohol, apples, bananas, barley, cheese, coffee, mango, onions, rice, tea, and turnips, and wheat were unknown in the Americas. Imagine an existence without any of those and you can hopefully begin to get a taste of the importance of the Columbian Exchange. Imagine Italian cuisine without tomato sauce or gnocchi and you can't help but wonder if this is why Columbus is so dear to many Italians. Imagine, on the other hand, genocide, slavery, and old world diseases and you'll understand why he's even more hated by many others.
WEST OF THE WESTSIDE -- THE SANTA MONICA MOUNTAINS
The Santa Monica Mountains are a traverse mountain range that stretches from the Pacific Ocean 64 kilometers east to the flood plain where the LA River is fed by the Verdugo Wash. The southern side of the eastern end of the range is almost always referred to as the Hollywood Hills. The central portion lies within LA's westside and the foothills are home to some of LA's most affluent neighborhoods (e.g. Bel Air, Beverly Hills and Pacific Palisades). To the north, separated by the mountains, is the San Fernando Valley. Technically, the Channel Islands are also part of the range, although they're separated from the mainland by water.

The western portion of the Santa Monica Mountains separates the Conejo Valley from Malibu and the neighboring communities that make up the Los Angeles district known as the Santa Monica Mountains area. The district borders Ventura County to the west and north, the San Fernando Valley to the northeast and the Westside to the east.
