Jim (Keely's dad) showed me pictures of a travertine hot spring in Turkey. Over there, they let people swim in the pools. I couldn't get the idea of what he was showing me through my brain. I just couldn't conceive of a mound of re-deposited limestone hundreds of feet long and dozens of feet high. The whole experience of this day was mind-numbing. From the pikas at Mt Washburn to an elk that peed all over himself outside Old Faithful Inn. If I wasn't there, I wouldn't believe it.
