Friday Field Photo #188: Cross Section of Alluvial Fan Barform
This week’s photo is from the mouth of Wildrose Canyon in Panamint Valley, California. My grad student (for scale) and I were out this way doing field work last spring and ended up driving by this nice outcrop on our ‘commute’ from the campsite to the field site.
We didn’t spend much time examining these deposits, but they are almost certainly Pleistocene (maybe Pliocene?) alluvial-fan deposits. Notable features include the poorly sorted, matrix-supported character and the large, inclined surfaces (dipping towards the basin, from right to left).
(You probably see an advertisement right below the post. Sorry to clutter up this content with annoying ads, I don’t like it either, but I would otherwise have to pay for hosting. This option is the least intrusive.)
