PO-2

PO-3

This is really an extension of PO-1 but to a slightly greater degree. Signs of travel are present and former ice screw placements may be present and possibly utilized.

This is the point where the PO scale begins to matter. You can now freely utilize the drafting mechanism. Twenty per cent of your hand tool placements are a gimme requiring almost no swinging to build a firm purchase. When you feel the need to place a screw you can choose from one or two of the pre-placed holes that other climbers have constructed for you or build your own. Foot placements have become slightly obvious.
