Owyhee Figs. 2 and 1...Last post of these, I promise.

Posted for co-author review...interloper review also accepted, but maybe not taken as seriously.

And it continues...

Sure I love making geologic maps, but this is becoming ridiculous. Just a few hours left on the Hole in the Ground map before I move way on.

Best guess Owyhee River path pre-West Crater lava (70 ka)

In the first attached image, I have drawn the pre West Crater lava flow course of the river. I based this on the presence of Tsv rocks in section along the western edge of the flow as well as the thickness of lava over Tsv, paleo Ryegrass Creek remnant, the big kipuka, Augerville...the big flat area bounded by large inflationary structures, the weird pressue plateaus with craters, the fact that landslides most often bound the margin of the river, and other space constraints.
Recall how I always point out that the desecrated mud stack seems to sit too low to mark the flanks of a pre-West Crater valley? Well, I accept it and used an estimate of the basal elevation to build a contour to see what other familiar areas the paleovalley floor could possible relate to...some of these areas include:
The prominent flat surface just below the northern exposure of the Saddle Butte lava...why have  I never stepped down on that thing?
The boulder line...the conspicuous line of basalt boulders that may relate to pre-Qbw degradation of the edge of the Qbs flow.

Owyhee Figure iteration 9076b-44m

Why is it that everyone finds something wrong with this except for me?

Back to being my own graphics department

Oh well. Take the good with the bad.

Psychedelic rendition of the NV-OR-ID borderland

Repeating color ramps are not only seriously awesome, they are also amazingly instructive about regional geology and geomorphology. Made this number with Globalmapper. The Owyhee River watershed is the conspicuous one.

Owyhee Map Draft 994a-2c

The never-ending map continues to never end. I call this good enough for manuscript review, don't you?
PS. Really missing graphic / cartographic support staff. Yikes.
