Yellowstone

If the Grand Canyon is about bigness, Zion about colors and Yosemite about rocks, Yellowstone is about water and fire. Cascades, boiling pools and geysers abound and the skeletons of trees burnt in the grand fire of 1988 add to the atmosphere of "after the end of the world".
This time, we took our precautions and booked a campsite early enough. We went to sleep with the yelps of coyotes and howls of wolves in the distance after dodging buffaloes erring on the road.
Of all the National Parks we've been to, Yellowstone is certainly the wildest. The wildlife is always close and I felt very lonely riding back to the camp at sunset under a purple sky. The only disappointment ? Old Faithfull: It goes "pshiit" in a puff of steam for five minutes and that's it; not even a pleasant smell of rotten egg as with so many other geysers and ponds in the park. But I am spoilt by so much beauty seen over the last three weeks, I guess.
