Crater
interior
The last eruption of this volcano left it in it's present configuration. The brown and tan layers are sedimentary rocks that the volcano's magma (liquid rock) pushed up through. The grey and black layes at the top are the ash and lava from eruptions. The lower part of the walls have talus cones of black and grey material derived from the top - this washes down and accumulates in cones. The right hand side of the floor of the crater has an alluvial fan (the sediment washes in from the right).
Fan
at bottom of crater
This fan has areas of dark sediment: regions where the sediment has been sitting undisturbed on the surface for a long time, so desert varnish has developed. Vegetation has also become established here. The lighter areas are where there are active stream processes - note the braided path of the channels. Ramapo students for scale at the bottom of the crater.
Ubehebe's
products
These rolling black and brown hills in the foreground and middle ground are cinders, ash and lava from Ubehehe. The light colored layer in the background seems to be the same light layer seen from Scotty's Castle, and I therefore assume that at least the lower part of the background hills are volcanic in origin.
