I've been working an old dumpsite just outside of Trona,Ca next to Death Valley. I drive out there daily at around 9:30am. Get off the paved highway then drive a mile over dirt roads to the excavation site. It's hot out here in August. An eleven year old boy died from the heat several days ago just up the road from Trona. It was in all the newspapers. Even the Drudge Report. I'm digging three to four feet down to find the good marbles. Am finding mostly old Akro Agate and Ravenswood Novelty Co. marbles. Most are in wet/pristine condition. At various depth are other artifacts. This morning I dug for twenty minutes. Quit before tyhe heat killed me. Found two antique marbles. One is a Ravenswood 'chocolate swirl' marble. Darn thing's pretty. Buried beneath it I pulled up a brass case several inches long. It is marked 'Justrite'. It once held carbide for the miners' lamps who worked the dozens of gold and silver mines which bracket my area of the desert. There are tens of thousands of artifacts buried out here.
