Question

yellowstone national park is unlike any other place i have ever seen. hot water gurgles up out of the ground where you least expect it, smelling like rotten eggs and spilling across oddly - colored rocks. yellowstone holds fascination for geologists and photographers. it fascinates me too.
established in 1872, yellowstone is our oldest national park. it lies mostly in northwestern wyoming and includes the spectacular canyon and waterfalls of the yellowstone river. if you drop a stick in the river, it will float downstream into the missouri river, then down the missouri into the mississippi river, and finally down the mississippi into the gulf of mexico. the yellowstone river gets its water from snow - fed streams high in the mountains. i have only seen the park in the summer, and even then i found enough snow on the high slopes to make a snowball.
the water that captures my imagination at yellowstone is not the chilly water of beautiful mountain streams but the strange hot fountains that spout from underground. whoever heard of so many kinds of hot springs? the variety of forms and colors is overwhelming. there are hot pools, mud cauldrons, paint pots, hot spring terraces, fumaroles or steam vents, and, of course, geysers. i do not suppose many people other than specialists can keep track of them all.
geysers are enough to think about for one day. old faithful is the most famous; it spouts high in the air, many times each day. perhaps you have seen pictures of it. personally, i prefer the little geysers the tour guides have not discovered, the ones along the roadside without even a sign to draw your attention. there are some 200 geysers in the park, or so i have heard. it must have taken a very systematic effort to go around and count them all.
