More rough terrain at Craters of the Moon.

Snake River Canyon in Idaho.
 
 

The Grand Teton Mountains.
 
 

Still at Grand Tetons, the prettiest spot I've ever had lunch.
 
 

After taking a ferry across the above-pictured lake, I walked to these falls.
 
 

Then I hiked up to a panoramic view.
 
 

This pond at Yellowstone straddles the continental divide, draining into both Atlantic and Pacific.  OK, I spit into it.
 
 

Old Faithful performed its duty.
 
 

A mysteriously blue thermal pool, part of Yellowstone's fascinating geothermal zone.
 
 

Tri-color thermal pools (red, gold, and blue).
 
 

A gurgling thermal mudpit.
 
 

A steamy thermal pond...
 
 

...sporting a rainbow of colors.
 
 

An elk grazed just across the stream from me.
 
 

The chipmunk welcomed me to this waterfall overlook.
 
 

I don't remember exactly how I got this close to an elk.
 
 

A very large bull elk lays in the grass while his harem grazes around the perimeter of the clearing.
 
 

In Yellowstone, just pull over where everyone else is, and find the animal they're off stalking.  Here's a young bull moose.
 
 

And sometimes the critters come to you - this buffalo walked right up alongside my car.  I stayed inside.
 
 

A much smaller mammal, this tiny pika regarded me from the top of its burrow (near center of picture).
 
 

About a hundred tourists were lined up along the roadside taking pictures of this black bear cub.
 
 

Strange orange-cream rock deposits.
 
 

A pair of deer or elk decided to lay down in the middle of a thermal area.
 
 

Almost like a frozen waterfall.
 
 

Roaring rapids (still in Yellowstone).
 
 

Eroding hillside above a river bend.
 
 

A gushing waterfall shoots into a canyon
 
 

Another canyon shot (this is the last Yellowstone picture).
 
 

Taking the scenic route through northwest Wyoming, I came to a very red mountain.
 
 

Here, a mountain looks to have lost a couple of its pieces.
 
 

A well known mountain in South Dakota.
