Mravenčí pilíř — 4, Bílá skála 4

The middle, most massive pillar with relatively solid rock that does not fall all the way to the path. Start to the left of the fall line of its edge with a couloir and a brittle, heavily overgrown wall down upwards to a small balcony to the left of the pillar itself. Traverse to the right to a crack in the left wall of the pillar (piton). Up the crack to a small balcony in the edge of the pillar (piton belay). Smooth little wall diagonally to the right upwards under the overhang and under it traverse down again to the edge (pitons). Up along the edge (sling, pitons) and higher transition to another small balcony in the left edge of the pillar (belay, sling). From there traverse to a large detached block and through the crack between it and the pillar back to the edge and to the sub-summit balcony. From there either along the edge, down over. depression, or to the right of the depression with a perpendicular corner to the top.
