Searching high and low on the slopes and cliff faces of the canyon so far, I have seen primarily the Tuscan Formation in all of its glory. However I have yet to find the fabled Lovejoy Basalt, which supposedly resides below it. (and certainly no Chico Formation which lies even below the Lovejoy)
I had hoped to have much greater success on the alternate side of the canyon because of its taller and steeper cliffs. Sadly this wasn’t the case.
However, that disappointment aside… I have seen many interesting stratagraphic structures and layers. Including cross-bedding, layering and possible folding of what appear to be almost exclusively ash flow deposits, of which I have multiple photos. (Generally ½’ to 6’ thick)
The canyon is on a slope, the downward direction of the slope is in the approximate direction of West, Southwest, which means the canyon and all it contains, ie: the creek, the rock formations, the main-road, all are lower in elevation at the mouth/foot of the canyon than they are at the top. This means that I probably just didn’t go far/deep enough into the canyon to see where the Lovejoy actually starts to become visible in outcroppings.
