A tall boulder on the far side of the Brickyard containing a couple of highball problems, most notably The Extremist.
As you come down the main trail to the Brickyard, take an obvious trail off to the left that mostly goes along the north side of a few boulders. The length of the boulder runs north-to-south, and the namesake problem is on the east face.
