Just another step in the trail. Peter guages the distance to the bottom of this boulder before making his leap of faith. Making your way up the valley is very, very difficult, but going back down is even harder and adds an extra element of risk - the effects of gravity.

Below, you quickly learn that the rocks with a thick coat of green moss offer the best footing. Not long after taking this photo, I gave up on keeping my feet dry and started slogging right on through many of the shallower pools. The decision to do so was made after the log that I chose to use to bridge a deep pool gave way, dumping me unceremoniously into calf-deep water. Freezing calf-deep water.
