I decided to dig through some of my old Viewmaster packets and scan some stuff. It was that, or do real work. Today it's all about Nature's Wonderland. Let's begin with this interesting ground-level view of three inhabitants of Bear Country. Three ITCHY inhabitants. May I recommend some Gold Bond Medicated Powder? I do like the fact that a Disneyland visitor would never be able to see these bears from this viewpoint, since they would be crossing the trestle some 15 feet up.
You didn't have to ride the Mine Train to see Nature's Wonderland... you could ride a mule too. Here's an unusual photo, apparently taken from the trail that was actually above Rainbow Ridge. If you look carefully at this photo you can see some stealth mules above the little buildings.
Again, a view that you won't see in any tourist photos, looking past the geysers and colorful bubbling pots of mud towards a Mine Train.
And finally, how about a rare photo taken inside Rainbow Caverns? I can only think of one other professionally-taken photo of the caverns, from a 1963 National Geographic (which you can see here on the Vintage Disneyland Tickets blog). Neither photo really does the thing justice (where's all the color?), but at least it gives a general idea of its beauty.
