Climb Little Agassiz Rock's arete closest to Big Agassiz Rock, if you don't know which direction is northwest. This is a classic, moderate problem. The crux is leaving the ground.
Climb the northwest arete. Downclimb the back. For orientation, there's a big quarry/industrial park to the east that you can see from the top of this hill.
Pad and spotter. There is a single glue-in bolt for toperope anchors, probably unnecessary for most boulderers.
