Shortly before the trail officially splits for the first time, as described on this site, there is an old-looking "trail" also heading to the left but blocked by timber. Do not take this timber-blocked route, and the "true" left route should be obvious a short distance after that point.
At the point where you first officially take a left turn, there is a small blue circle near the ground. A small arrow points to the path heading right, in the direction of the blowout.
"Got tight last night on absinthe and did knife tricks. Great success shooting the knife into the piano. The woodworms are so bad and eat hell out of all furniture that you can always claim the woodworms did it."
