Is this a bunch of students with too much time on their hands messing around with rocks on death valley and damaging a good race surface? Sounds suspiciously like the Death Valley equivalent of "Crop Circles" to me. I knew you'd like it VBG. Parts of Death Valley You could be there & look for yourself in about 3 hours, right? (BTW, Rare personal note --- I was supposed to be a park ranger per some old school aptitude test long ago GG.) consist of a dry lake bed with something like around 2" rainfall per year. Someone "might" be able to choose a morning before a forecasted rainfall and load up their pick-up truck with a water tank and a suitable rock. Then lay down a long narrow line of water to soften the dry ground, turn around and straddle the softened mud, drop the rock, and pull it with some rope creating the scrape marks shown in the pics. Pretty good prints, eh? As soon as it rains, as per the forecast, it removes any light tire tracks that may have been made in the dust but probably isn't enough rain to remove the scrape marks... then Waala, OOOOOoooo (insert Twilight Zone theme-song here), "A Mysterious Moving Rock" has suddenly appeared. LMAO! What does the lint think? Examine pics well G. -- Cliff |

Pretty good prints, eh? It's a "dry lake bed", ever been on a dry lake bed? Some of them are really "hard", not as hard as concrete but hard enough to not show much in the way of prints beyond disturbing any loose dust on top. Then the mud shown was dry when moved by the moving rocks? But the movers left no tiretracks? Why do you suppose that they call it a "lake bed"? BTW, At least some of those rocks moved *uphill* it seems ... -- Cliff |
