Each science experience is amazing, interesting, and fun in its own way. If I had to choose,
however, my favorite would be conducting dye traces at the Grand Canyon. This work involves dumping a colored non-harmful dye into the ground up on the plateau above the canyon, then monitoring springs in the canyon to determine where the dye showed up. This is simple science. But the results tell us an incredible amount about how water moves below our feet and it never seems to do what we expect.
