@Allochthonous holding his spiffy new rock drill, prior to its first use: drilling core samples from the muddy intervals of the Tyee Formation road cut shown here. The drill is essentially a chain saw engine with a tubular corer attached to the axle instead of a gear to drive the chain. The pump canister holds water, which feeds through the black hose, to cool the tip of the corer.
