Frances Humphrey Lecture Series: Sliding Bones of the Smith Creek Playa, Nevada, and their Similarity to Racing Rocks in Death Valley, California
Dr. Baumgardner observed five skeletal elements or bone groups resting at the ends of furrow-like trails inscribed in the playa surface. These trails, with their bones, appear similar to the phenomenon described as “racing” or “sailing rocks” that is best documented from Racetrack Playa in Death Valley, California. Recently favored explanations for such movement involve combinations of water, low temperature, microbial mats, and wind. These options and the significance of such movement by skeletal material will be discussed in this lecture which begins at 6:30 pm. Doors open at 6:00 pm.
