I found some pictures I took while on a trip to Utah back in 2007. I was in the House Range area of Utah, west of the town of Delta, digging around in the Wheeler Shale. The Wheeler Shale (middle Cambian age) is well know for it's abundant and well preserved trilobite fossils and I was looking to add some to my collection. There are a couple of pay dig areas in the area like U-Dig and A New Dig but not many know that you can literally find trilobite fossils in at just about any exposure in the area.
This is a prospect that I saw from the road as I was driving around. Someone had come it and was digging shale out of the ground and splitting.
Some of my finds.
