A rare quartz wedged rock
This is the first example I have seen of quartz used as a wedge in a split rock. So this is pretty rare. Given that split rocks are suspected to represent doorways to the underworld, I always thought the absence of such quartz as a wedge was because you would not be leaving this kind of amplifier/ transmitter at an entrance. But, right or wrong, here is an example from east of Whitehall Reservoir.This leaves my theory scrambling for excuses to the effect that this must have been a particularly friendly spirit.
