The trap shown in these pictures is presumed to have been
commonly used in the southwest. Many artifacts have been found. The most
commonly trapped animal was assumed to be pack rats.This type
of split-stick trigger relies on the friction between the ends of the
pieces of wood. This friction is due in part to the pressure of the
upper piece of wood against the bottom piece. As well, the two ends must
be a bit rough or there's no way that they would stay together.
This type of trigger could be extremely sensitive.
Bait is applied to the "pointy" area.
