"Ben-Hur: A Tale of the Christ" (MGM, 1925)
The rock was making appearances in the movies decades before Clayton Moore first rode up. Above is a screen shot from one of its early appearances, back in the silent movie era. That's Lone Ranger Rock (not yet known by that name) in the top right corner, with a group of characters from biblical times standing on it and a whole mob gathered at its base.

First, here's a short clip by David August:
This one, posted by OverwhelmingSilence, is a bit more in-depth:
You can see another cool video about a fan visit to Lone Ranger Rock by going to this YouTube link. That one has embedding disabled, so I can't post it here. But it's worth checking out.
Poison oak at Iverson, not far from Lone Ranger Rock
Poison oak is easier to spot after it starts turning red — and it also gets more potent then. But it's dangerous even when it's green, which is one of its sneaky and unpleasant characteristics. (Others include making you itch like heck, being resistant to just about any kind of treatment, and sticking to clothes and everything else, meaning you can get it from just touching your clothes.) In case you haven't had the "pleasure" of coming into contact with it before, take my word for it: You don't want to. If you're not sure you can recognize it in the wild, try not to touch any plants, and be careful when handling your shoes and pants after you hike in the area.
Western diamondback rattlesnake
The other warning is about snakes. A number of different species live at Iverson, but the ones you have to worry about are the rattlers. I still have yet to see my first rattlesnake at Iverson — the above photo is not shot there — but I've encountered other snakes at the site, and that was scary enough. The rattler is known to live there, so be careful about where you step, and if you do see one, give it some room. Word is they don't usually hassle you if you don't hassle them.
Below are Amazon links to some of the DVD packages of the old "Lone Ranger" material, with a warning that many of the best packages go out of print from time to time.
