Coming up Slickenside Ridge past the last little slickenside, we came upon this whopper.
It's hard to tell from this photo, but fractured, brecciated, and slickensided dike rock on the far side of the fault plane is juxtaposed against more dike rock, which is what I'm standing on to take the photo. The fault is dipping more or less to the east, and the slickenlines are almost straight downdip (slightly oblique).

|An even closer view of the lower part of the slickensided surface.|
We also noticed a nearby cross-cutting fault of minor displacement running about east-west, offsetting this fault and the faulted dike-dike contact by a few feet. Apparent offset across this cross fault was south side to the east (the fault was poorly exposed and dip direction wasn't obvious).

|We viewed the hill again a little higher up, from this little shadow created by an outcrop of quartzite.|
Our hike wasn't over, though...
