This was along a pullout approximately 4 miles east of Mammoth Hot Springs.

Passing the bison on a bridge. It's amazing how ostensibly unafraid bison are of this type of human activity.

Not sure if this is a black bear or a grizzly, but it looks like a black bear. I can't determine exactly where I took this, as I provided no context clues. I'm pretty sure it's between Lava Creek and Floating Island Lake, at around the coordinates 44.952234, -110.478641. I don't provide a link because I'm not sure of them!

Drove a bit along the NE Entrance Road (leads to Beartooth Highway) and doubled back.

Great view of the Yellowstone River near Tower Junction & Calcite Springs.

The Yellowstone River bifurcates to give off the Lamar River just north of here (near Tower Junction). Soon thereafter, the Lamar River bifurcates to give off Slough Creek.

Very windy. Great short hike to a small hill overlooking the area.

These falls are twice as high as Niagara Falls, at around 300 feet. You can hike to the brink of the falls using the Brink of the Lower Falls Trail. As the sign will indicate, it's only a 3/8 mile hike but it's a 600 foot drop! At around 12 seconds, I pan to the lowest observation location of the falls, which is bigger. I'm at the smaller one that's slightly up the trail. The next video is from the lowest observation location.

This is from the lowest observation location, and shows all that water spilling over (as well as a rainbow.) At its peak, the volume of water going over these falls can be above 60,000 gallons a second.

I did some research on the USGS' website on the Yellowstone Lake Outlet measurement for 2009, and at least at that location (which is not here but upstream) the flow was around 20,000 gallons per second for this day. Peak for 2009 was around July 4th or so at 50,000 gallons.
So, I'm not sure how much more water is added to the Yellowstone River from the Lake Outlet to the Lower Falls, but I'm sure those numbers are increased.

This is Lewis Lake, not Heart Lake. Heart Lake isn't visible from the road.
