A reminder- it is unsafe and illegal to approach wildlife within distances posted all over Yellowstone NP. In my case the ELK came to wherre i was from a couple hundred yards initially to less than 20 feet at times. I slipped down between two three foot high rocks and moved as little as possible during my close encounter.
Here's where they were when I first set up- check out the calves having a good time.

The Pansonic Lumix camera has a 12: 1 zoom that sure is handy


And a couple still shots that I like




ARE the video clips playing for you?
