I freely admit that the first time I saw the Eagle Rock I thought it got its name because it's shaped like the head of an eagle.
It doesn't take long to find out that the Eagle Rock is named for the shadow cast by the formation in the upper center of the rock, which looks like an eagle with outspread wings. (I still think the rock looks like an eagle head but that either makes me crazy or makes the name doubly appropriate.)
Eagle Rock is also the name of the Los Angeles neighborhood that shares part of Pasadena's western border. To get there, all we have to do is drive or bike west on Colorado Blvd. for a few minutes. Eagle Rock was once its own municipality, incorporated into LA in 1923. The pre-incorporation City Hall and Library still stand on Colorado Blvd.
It's a funky area, with mostly independent businesses--coffee shops, clothing stores, restaurants, and the president's Alma Mater. I'll head over for a new installment in the Coffee Shop Quest one of these days.
Wikipedia's article about Eagle Rock has a photo taken from almost the same spot where I took this one. Their pic shows a deer in the bushes (it'll give you some scale) and a lot of dirt in the foreground, where now there's a lot of asphalt.
