Not incidentally, these photos were all taken during the early days of this year's Death Valley "superbloom." We'll see some wildflowers in this post, but I'll be concentrating on the turtleback or detachment fault surface and not the flowers.
|The Badwater Turtleback fault surface, looking north. Part, but not all, of the apparent curvature in this photo is from the 18mm wide-angle view (27mm in 35mm equivalent).|
|The apparent dip on the alluvial deposits is shallow, dipping slightly back to the east. This is only apparent dip, however.|
|In this photo, you can see a more steeply dipping fault cutting the fan deposits in the hanging wall of the main shear zone. The slightly steeper hanging-wall fault may flatten toward the main shears, but that's really unclear.|
|Here we're looking up the plane of the fault surface, a kind of disorienting view.|
|This photo shows more older alluvium in the hanging wall of the turtleback fault surface, with the younger alluvium of a talus cone to the right. Notice the nice greenery with smallish flowers on the talus.|
|MOH looks up at the fault plane on the south side of the little drainage area or canyon near the base of the turtleback surface.|
|The same surface, perhaps a little closer.|
|Fault surface with wildflowers.|
|The faint slickenlines are running across the photo here (same piece of float).|
|The turtleback fault plane is exposed in the shadows of a "slot" canyon just south from where we hiked up. Note the greenery with tiny wildflowers all across the fan.|
|And here's one of the tiny flowers. Does anyone know what this is?|
|The Badwater Turtleback fault and a bit of desert gold.|
|We take one last look at the alluvial fan, the flowers, and the Badwater Turtleback. The flower show is dominated by yellow desert gold and purple notch-leaf phacelia.|
|Say goodbye to Badwater, before we head north.|
