The correct answer to question 4 indicates a lot of years. Could we have really screwed up the calculation, so it is way off? Well, suppose that for all of history until yesterday, Happy Valley was as wet as the wettest places on Earth. (Making central Pennsylvania that wet is almost impossible, because the wettest places on the planet have climatic characteristics that are not possible in Happy Valley. But, just suppose.) Then, the stream would have been carrying rock away faster than we calculated above. In addition, suppose that lots and lots of limestone from Happy Valley has been carried away as chunks in the stream, again meaning that rock has been removed faster than we calculated. (There is almost certainly a grain of truth to this one, but not a lot; observing Spring Creek shows that most of the rocks in transport are actually originate in the mountains--the valley rocks mostly dissolve, and the mountain rocks wash down. But, just suppose.) Call the time to hollow out the valley, from question 4, an even 10,000,000 (10 million) years. Now, if the rock was actually removed 12 times faster than used in that calculation (about as much faster as is possible with what we just told you), what would the new estimate of the time to hollow out the valley using this new, faster rate be? ________yr (your calculator may not show exactly what is listed below; if not, take the one that is closest). (If you're not sure how to proceed, ask yourself this question: if you dig faster, does it take a longer or shorter amount of time to reach the bottom?)
