Staying on the Rivers of America is this shot of a nearly empty Mark Twain being loaded. It appears that Tom Sawyer Island was closed with several items under tarps.
While on the Mark Twain, the photographer took an image of Cascade Peak.
The best slide is this one of the Disneyland band in their 25th Anniversary uniforms marching down Main Street. The simplicity of the 25th Anniversary Celebration is shown by the simple lamp post plaques. No silver painted atrocities like the Golden Dumbo, Casey Jr., Jungle Cruise Launch or bling added to the Mark Twain or Sleeping Beauty Castle as was done for the 50th.
