In situ rock fragmentation, with widening of fractures assisted by wedging of pebbles and granules

Currently a gravel quarry, this deposit is a Gilbert-type delta, with flat lying topset, dipping foresets, and flat lying bottomset (not visible). It's being actively mined, and no longer exists in this form. Photos taken in 2014 with handheld camera, walking around this outcrop in nearly 360 degrees.

Photos taken in 2017 during a geologic field mapping course. Location is only approximate. They don't look like normal faults from this angle (the clipboard is horizontal), as they have been tilted since they formed.

Geologic outcrop shows a contact between a conglomerate and sandstone, with an old channel scoured into the sandstone at the base of the overlying conglomerate. Subsequently, the rocks were faulted and tilted. Location is approximate. The model is scaled and oriented to north and gravity.

Faulted sandstone layers caught up in a plunging anticline in Gower Gulch, Death Valley National Park. Location is approximate. The model is scaled and oriented to north and gravity.

Alluvial fans spread out from the northern edge of the Panamint Mountains in Death Valley National Park, and extend to Mesquite Dunes. A recent (March 2019) flashflood originating in the mountains left this exquisite deposit. The location is approximate. The point cloud is scaled and aligned to north and gravity.

Several thousand years ago, Ubehebe crater formed when rising magma encountered saturated sedimentary rocks. The groundwater flashed to steam, and ejected a large amount of material leaving a large hole in the ground. Rocks left behind show some evidence of the hydrofracturing in the form of shattering. The point cloud is scaled and aligned to gravity. Location is approximate.
