This boulder is to the Northeast of the large, prominent spire on the South side of Mt. Baldy. Look for a large Ponerosa Pine on the South side of the boulder, near a crack running up and right which hosts the boulder's namesake "Obtuse" (V6), a slopey, awkward problem. There is a large deadfall to the south of this boulder.
