Located in the Garden of the Gods next to the larger and more widely exposed Sphinx, or Eagle Beak (not seen here), the Phantom tends to be undeservedly overlooked. But it does get screen time in a lot of old movies and TV shows if you know where to look and can get past the "star power" of neighboring rocks Sphinx (aka Eagle Beak) and Tower Rock (aka Indian Head). The Phantom is typically seen just to the right of the Sphinx, if the camera happens to wander over that way.
"The Lone Ranger" TV show (1949) — the Phantom in background
The Phantom did play a featured role in an early episode of the Lone Ranger TV show, as seen above (with the footage also used in the Lone Ranger movie). In the shot above, the Phantom provides the background during an ambush sequence that sets in motion the whole Lone Ranger saga. Please check out this blog entry, which talks more about this famous scene.
