From Salt Lake City up through cowboy country, geyser land, and back down to the turquoise waters of Bear Lake.

Everything cool, weird and wonderful about where we're headed.
Under Yellowstone, rain water trickles down to rock heated by magma. It superheats, pressure builds in a natural underground plumbing pipe, and — BOOM — it blasts out. Old Faithful fires roughly every 90 minutes, up to 55 m high (that's higher than a 15-story building).
The colors are ALIVE. Rings of heat-loving microbes called thermophiles each like a different temperature — orange and yellow ones live in the cooler edges, while the center is too hot for anything, so it glows pure deep blue.
The whole middle of Yellowstone is one giant volcano crater (a caldera) about 50 km wide. The magma chamber under our feet powers every geyser and hot spring. Last mega-eruption: ~640,000 years ago. Scientists watch it 24/7 — it's calm.
Most mountains rise slowly from foothills. The Tetons just... don't. They shoot straight up 2,100 m from the flat valley floor, which is why they look unreal. They're the youngest mountains in the Rockies — and still growing along an active fault.
Wolves vanished from Yellowstone for 70 years — until 1995, when 14 were brought back. Elk stopped over-eating the riverbanks, trees returned, beavers returned, and even the rivers changed shape. One animal rewired an entire ecosystem.
Bear Lake's crazy turquoise color comes from tiny particles of limestone (calcium carbonate) floating in the water, reflecting the sky. It's 28,000 years old and has fish that exist nowhere else on Earth.
Half a mile of underground rooms dripping with stalactites and stalagmites — some look like frozen waterfalls. It stays 4°C all year, even in August, and it took water hundreds of thousands of years to sculpt.
12,000 years ago this was the bottom of a giant ancient lake. The water left; a dead-flat crust of pure salt stayed. It's SO flat and SO hard that it's where humans go to drive the fastest cars ever built.
110 km of switchbacks climbing to 3,337 m — above the treeline, past alpine lakes and (sometimes) August snowbanks. TV journalist Charles Kuralt called it the most beautiful drive in America.
These are also your targets in the Wildlife Spotting game — points shown on each card!
2,000 lbs, runs 35 mph — faster than any Olympic sprinter. Babies are orange and called 'red dogs'.
Males grow a new set of massive antlers every single year, then drop them like a mic.
Tallest animal in the park — can dive 5 m underwater to eat lake plants. Check Oxbow Bend!
Wingspan over 2 m. Spots a fish from 3 km away. America's bird, obviously.
2nd fastest land animal on Earth (88 km/h) — built to outrun cheetahs that went extinct here.
Great tree climbers. Despite the name, they can be brown, cinnamon, or even blond.
The shoulder hump = pure digging muscle. Can smell food from miles away. 100-yard rule!
The jackpot. Roughly 100 wolves in the whole park. Lamar Valley at dawn/dusk is your best shot.
Rams' horns weigh up to 14 kg — more than all their other bones combined.
Hunts by sound — that famous head-first dive into grass is aimed by its EARS.
Nature's engineers. Beaver dams create ponds that dozens of other species need.
Often mistaken for a wolf — coyotes are half the size with a pointier face. Now you know.

First person to spot the animal shouts it out — driver confirms — tap the animal, pick the team. Rarer animal, bigger points.
Teams take turns. Read the question out loud, team huddles, then reveal. Correct = +10 to that team.

One actor, no words, no sounds. Everyone else guesses. If the actor's own team guesses within a minute → +10.
Two of these are 100% real. One is a lie. Discuss as a team, then tap your pick. Catch the lie → +10.
Deal a challenge, hit start, and one team shouts 5 answers before the buzzer. Make it → +10. Teams alternate.
Each team locks in a guess out loud. Reveal — closest team takes +10. No peeking, Trail Boss.
