This is the huge boulder nestled in the trees across the valley that is visible from the top of the hill next to Tweedy Bird Rock.

It has a rounded top and a steep face on the opposite side of the approach.

The quality is good down low and gets sandy at the top-out

Hike past Tweedy Bird Rock and hike straight north across the creek bed and into the maze of small trees, the huge boulder is visible from the start of the approach and you can lose sight of it when you get into the maze. Continue North and you will approach the boulder from the back and you cannot see the lines until you walk around the boulder.
