Not completely certain of the problem's name, but the boulder is covered in yellow lichen and on the bottom right corner it almost looks like an etched "W" in the lichen. (See photo)
Starts just left of the "W". Pull up moves to a dish in which you mantle off of (crux). Move slightly right to thin moves up top. It's tall, bring pads.
The grassy knoll area is on the backside of Quartz Mountain. W Boulder is located on the northern most end of the grassy knoll, perched up on a small hill. See photos.
