  To the west, start onto the east-sloping Mojave River fluvial plain, a transition that is marked in many places by small playas; note rolling surface with high ribs that represent inverted stream channels (formed when stream deposits with coarse clasts are eroded, forming resistant ridges that once marked the channels) of the river as we continue onto the plain.
  Junction: Military Road

  Powerline road cuts (545715 3884925 ) consist of Pliocene gravels near? Interfingering? with playa sediments; provenance of gravel packages; tectonic patterns (Miller).
  Desert Symposium Field Trip Stop 2017-2-6. Miocene and Pliocene sediments at the south edge of Fort Irwin.

The gray, silty playa sediments to the south have not yielded age diagnostic specimens. Farther northeast along the powerline road, the Pliocene sediments are exposed conformably below, and above, the 5.6 Ma Bicycle Lake basalt. Elsewhere, they contain a 3.4 Ma ash (Miller and Yount, 2003), suggesting that deposition of the Goldstone Gravels ranges in age from approximately 6 3 Ma years. Therefore, we must search for the 6 million year unconformity between the 12.6 Ma Miocene sediments and the 6 million year gravels and silty playa sediments.
