Synchrotron X-Ray microtomography 3D image (a) and cathodoluminescence slice (b) from the same reentrant-bearing quartz crystal from the Lava Creek Tuff. The reentrants are in darker blue in (a) and the black cavities in (b). Note their relationship to quartz growth bands. Red domains are small magnetite crystals.

The sediment sampling project was intended to provide insight into the presence of microplastics in the Colorado River basin. Samples were collected at every campsite that had an adequate supply of sand.

For Team D, this was our first morning on the river, putting-in at Split Mountain campground in Dinosaur Nat'l Monument. The whole group was very excited as none of the expedition members had ever rafted this section of the Green River.
