The boulders and rock formations that scatter Obi Obi creek creates a maze for the water to pass through, the main flow is slowed through the tighter turns, this scene shows a quiet slow moving section where the creek bulges under a tree. the water along the rock wall is surprisingly deep. There is no room to move in the rainforest behind, the trees are so tight to the creek that the easiest path for a hiker is through the water.
