Hello again, I can only answer your questions from my own exprence. Geysers and Hot Springs go togeather. That is if you go to Yellowstone National Park you will see Old Faitfull a Geyser. In the park you can find Hot Springs both are there becouse it's a Volcaino. DO NOT SWIM in the Hot Springs here. You can find Natural Hot Springs all around the Country that you can swim in. Have fun.
