When you visit some of America's national treasures, don't get too close. Two men learned that not only is it dangerous, it can get you in trouble with police. Marci Gonzalez is in los Angeles. Marci, the pictures with this one say it all. Reporter: They really do, Eva. And they're being used in the case against these guys. The woman who snapped them posted them to a group dedicated to highlighting people who break the rules at the park writing that everyone watching was in disbelief of what she called the complete stupidity of the men's actions.

This summer this 9-year-old girl thrown into the air left with minor injuries after getting too close to a bison while with a group visiting old faithful, and last year a group photographing these elk fighting when one suddenly charges forward, knocking a man to the ground.

The guys captured in those photos at old faithful will now have to face a judge in federal court. Dan. I mean, are these warnings that we really need to repeat?
