I first discovered that there were some ruins ripe for exploring on Catalina Island thanks to a KCET video on the former Island Mountain Railway, built by the Banning brothers who owned Catalina Island at the time. (You can watch the video at the bottom of this post.)
The funicular connected the town of Avalon to Pebbly Beach—which was necessary because Pebbly Beach Road hadn't been built yet.
circa 1914 (Photo: California Historical Society, via USC Digital Libraries) I still haven't made it Buena Vista Point—where a Swiss chalet-style power house for the incline railway attracted tourists to Mount Buena Vista Park, at what was also known then as Avalon Summit.
Google Satellite viewThere's apparently a concrete foundation and maybe some other rusty ruins left up there. But there's something else that can be seen, farther down the hill, right next to where one of two funicular cars used to run along the west side of the hill: the old Greek-style amphitheater.
