There wasn't much evidence of the exfoliation going on that I could see, though I could tell the rock looked different. My family's been going to Twain Harte for years and the rock looked more angular than in seasons past. <br /><br />It's funny, I was standing on the rock looking at an unweathered patch of the granitic rock, (the rock has been covered with graffiti for years and years so seeing a big patch of fresh rock and no graffiti was strange), and thought "I wonder if this rock every slabs off?" I now know that it does, and in spectacular fashion.Anonymoushttps://www.blogger.com/profile/07147201274166499850noreply@blogger.comtag:blogger.com,1999:blog-5211670216140060946.post-40440727830371798512014-09-18T14:53:41.768-07:002014-09-18T14:53:41.768-07:00My guess is it may have something to do with the n...My guess is it may have something to do with the normal amount of heavy ice which is located over the granite in winter, and without said ice these last few years (or reduced amounts) the load above it is not enough to keep pressure on the granite.
