Pasadena is a beautiful city located in Los Angeles County California. The city of Pasadena was one of the earlier cities developed in the San Fernando/Los Angeles region and holds a lot of southern California history. The city of Pasadena and was the 4th city to be incorporated into Los Angeles county in 1886, after major cities such as Anaheim and Los Angeles. Pasadena is the 9th largest city in Los Angeles County as well as the 180th largest city in United States, as of 2012. Pasadena is known for many great things throughout the community and attracts people from all over the world. Many people come to see and experience Pasadena for tours, shopping and to visit its many production studios, landmarks, celebrity lifestyles and attractions.
Pasadena is generally a higher class community with approximately half of its population being of Caucasian decent, 10 % African-American, 15 % Asian and approximately 35 % Hispanic or Latin backgrounds. Other ethnicities also reside in the region, but most of its residents contain the listed above. The city was heavily occupied by the native tribe Trongva, later known as the Gabrielinos who slowly began depleting after Spanish settlers moved in. As the United States Postal Service began developing, regions began having to their name themselves accordingly. Pasadena meaning “Of the Valley” went through many names such as “Granada” and “Indianola” hoping to stick to their Spanish culture. After many meetings and names, city officials finally decided on Pasadena, which was a name recommended by Michigan Chippewa tribe leader who was friends with a Pasadena Council member.
Pasadena is geographically located just at the base of The San Gabriel Mountains, and is surrounded by hills and valleys. The city is also located on the Raymond Fault line in the San Rafael Hills. One of Pasadena’s most well-known landmarks, the Rose Bowl is located directly in The Arroyo Seco, which is a stream that runs from the nearby San Gabriel Mountains, through Pasadena, a few other cities and then finally leads into the Los Angeles River, which is a huge water source for most of Los Angeles County.
Pasadena is located in the Northern area of Los Angeles County and is considered a central location being that it’s located near 4 main Los Angeles freeways, which are all under the jurisdiction of the city of Pasadena.

This Freeway plays huge role in commuters and southern California professionals as it connects Pasadena with the San Fernando Valley and San Bernardino County cities. Another very important freeway in the region is the 134 which runs opposite direction as the 210 and also starts near Downtown Pasadena and travels West bound, leading to the 210 and Valley cities.

It’s a shorter and beautiful commute to the other side of the mountain but has some harsh weather conditions during the winter months and is common to mudslides and rock slides.
