North of Tetons there is Yellowstone – the oldest national park in the US. The campgrounds are very popular and therefore usually full. There are few though that can be booked in advance and as we learned there are many cancellations. Thanks to Teton grocery store’s wifi and Wojtek’s patience we managed to book a site at Madison camprground. This meant we did not need to wake up in the middle of the night and look for a free site around 6-7 a.m.

The map suggests this park will be huge and dear Gods it is! It takes easily 1-2 hours to move between places and can take even more if bisons  decide to chill on the road. We spotted only one herd in Tetons but there are so many here that we stopped paying attention after three days. I read that Yellowstone has the biggest number of geysers in the world. Yes, there are geysers, shooting fountains of water into the sky, there are bubbling mudbaths, steaming fumaroles and hot springs. Their boling insides are so intensely blue with colorful water tongues on the sides, where the water is cooler. This makes a perfect habitat for microorganisms and algae which dye water in different colors depending on temperature. And so these colorful glissandos are created. Stinking rotten eggs, dangerous and unbelievable. All of them lying above a supervolcano. If it explodes one day, everything in the 800-mile radius will be covered in  ash (1 mile is roughly 1,5 km – do the math).

The mornings are cold, +3-5 degrees cold. The fog covers everything and even the Great Prismatic Spring is invisible. But then the sun comes up, the fog disappears and the temperature rises to 30 degrees, giving us sunburnt noses and foreheads.
