The Green Monster is the premier boulder in the Rapid City Area. This boulder is a proud beautiful looking boulder on the hill side seen from the parking lot and Omaha Road. Most climbers tend to try climbing the Green Mile V10. This problem was established by Josh Dreher. On the second ascent Dan Dewell broke a crucial hold in the horizontal crack. Talking with Dan and Josh both have confirmed its either way harder or not possible anymore. If it does get done and sees a third ascent it would be technically a whole new climb and grade.
