Lake Avenue is a major north–south feeder road for the Pasadena and Altadena communities in Los Angeles County, California. The road was developed in the mid 19th century and takes its name from a lake which was located at its southernmost end known variously as Mission Lake, Kewen Lake, and Wilson Lake reflecting different owners of the land. The lake bed still exists as a municipal park (Lacy Park) in the City of San Marino just south of the Raymond Dike, but it holds no water. It has been surrounded by residences who are served by a crisscross set of roads that dip into the edges of impression and back out the other side. Lake Avenue is approximately in length. Transportation Metro Local line 662 and Pasadena Transit line 20 run on Lake Avenue: the former starts at Del Mar Boulevard and the latter through most of Lake Avenue between California Boulevard and Woodbury Road. A Metro L Line station is located at Interstate 210 under Lake Avenue. In Altadena The northernmost end of the road lies at the very foot of the San Gabriel Mountains in Altadena and immediately accesses Las Flores Canyon. The first resident of Las Flores Canyon was the Forsyth Ranch. It sold in 1919 to Mr. Cobb who had an enormous and fascinating estate on the alluvial fan which emanates from the Canyon. Las Flores was also known for its small and short-lived gold mining operations there. The Cobb Estate was deeded to the United States Forest Service as a free growth Arboretum in 1967. The gates on Lake Avenue mark the entrance to the estate which still has its long, paved, curving driveway which leads to the site of the defunct manor. The adjacent trailhead of the Sam Merrill Trail also leads into the canyon from Lake Avenue. This is the origin of the local term "top of Lake," which refers to the northernmost neighborhoods. In the days of the Red Car in Altadena (1902–1941), Lake Avenue was known as the short line, or Oak Knoll line. Oak Knoll is the street into which Lake Avenue transitions with a slow curve to the right and then back to the left. The Pacific Electric cars came up from a switch on the Huntington Drive line below the famous hotel of the same name. The “short line” was a shorter way to get to Lake and
