Still along Yellowstone Lake, probably mighty close to Steamboat Point.

Yellowstone Lake laps right up against the road here.

Somewhere near the road intersection at the north end of Yellowstone Lake lurks beautiful buffalo like this.

More buffalo!

And there's a little baby buffalo! Aaaaawww!

A video showing some of Yellowstone's most famous features: sulfur pits! Remember, the area was inhabited by humans since at least 9000 B.C., and the piping hot mineral waters and steam provided much of their medicine. (To be sure, most of these traditional medicines worked better than some of the junk Big Pharma sells us now.) In the second segment of this clip, you can hear a little boy saying, "It stinks!" But the secret is in the aroma! The final segment of this theatrical release features Black Pool, which is clear, blue, and deep. It was cold outside, and the steam worked wonders at warming the air.

Water in one of the cauldron-like sulfur pits boils. Incidentally, you should never diverge from posted paths anywhere near the sulfur pits (as tempting as it looks). That's because the surrounding ground is just as hot as the pits and may cave in without warning - landing you in the burning waters underground. Never enter the water in a sulfur pit. Every so often, people are scalded or even killed by diving into the water. Not only is the water very hot, but the water in some of these pools is also so acidic that it can instantly dissolve even the toughest pair of boots. Throwing objects into the sulfur pits is just as ill-advised, for that may ruin the pit.

Sulfur gas rises from this pit, and you can see more plumes of steam in the background.

Probably back at Yellowstone Lake.

Mountains bip into view along the lake.

Whaddya know! More sulf! This has to be the sizzling land along West Thumb.

A sulfur pit rips a wafto.

An attempt to show just how deep these sulfur pools are.

This is Abyss Pool, which is just as amazing as all the other sulfur pits.

The area with Abyss Pool, Black Pool, and their comrades features this boardwalk along West Thumb - actually an appendage of Yellowstone Lake.

This stretch of road runs between West Thumb and Madison, and here we're at the ramp to Old Faithful.

A video of Old Faithful erupting! I planned on using a Go West song for this clip, but the IFPI's perjured DMCA complaints have put the kibosh on that. Remember that Metamucil commercial in the early 2000s where the ranger poured Metamucil into Old Faithful? The National Park Service had a fit over that! The National Park Service was so outraged that it didn't need Metamucil but it sure needed some Imodium! The agency said of the Metamucil commersh, "This advertisement goes against all of the National Park Service's efforts to encourage people not to put foreign objects into the thermal features."

Getting off the road to Old Faithful and back onto the main road.

The West Thumb-Madison road near Old Faithful.

The same road, with gobs of sulfur pits emitting steam.

Yet another of the famous sulfur pools.

Sulfur gas corrodes metals and ruins appliances. That's why chemistry class is so much fun!

Another video showing sulfur pits releasing their magnificent gases. But remember, what this really does is remind us that all of Yellowstone sits atop an active volcano - one of the world's largest. And if there's a major eruption, it could potentially be the deadliest ever and spread ash over the entirety of several states.
