This paper uses 699 single-grain (U-Th)/He ages in 12 different sizes of sediment to trace each clast back to its origins on hillslopes. We also developed a new analytical framework to analyze this big dataset, which incorporates some of the complexity of mountain landscapes. If you’re interested in sediment – where it comes from, how it breaks down, where it ends up – please check it out!
