I don’t have a lot of information on this photo, but from what I can piece together, it appears to be from the late 1890s when the Tally-Ho carriages would take groups of locals and tourists from Los Angeles (which back then was pretty much just downtown LA) where they would pick up passengers at the main hotels and take them through Pasadena, where more people would join the convoy, and then onto Altadena, where most of them would ride the funicular up Mt. Lowe. Like most trips back then, it would have been at a leisurely clip-clop pace through an untamed landscape like we can see the background.
