Personally felt it was easier than the V4 grade it's given in the guide book.LocationOn the boulder that's on the right side of the stairs, slightly NW of the main rock. Just right of Left Arete and just left of Rimshot. Start on the two okay-ish pinches about 6 feet up, or left hand can start on the (probably worse) sloper.ProtectionPad maybe since you're above the stairs.Routes in Mortar Rock1Left AreteV0+Bouldering2The Girls' Problem (stand)V4Bouldering 3The Girls' Problem (sit)V5Bouldering4RimshotV2-3Bouldering5The Hand Traverse (Warmup)V1Bouldering6Pipeline TraverseV6Bouldering7Red's RevengeV2+Bouldering8Nat's TraverseV8Bouldering9Baby Nat'sV6Bouldering10Smale Frye TraverseV8-9Bouldering11OutbreakV10Bouldering12InfluenzaV10Bouldering13Over the BulgeV3Bouldering14Sunshine ElluminatiV9Bouldering15Sunny SideV6Bouldering16Sunshine EliminateV8Bouldering17CherriesV9-Bouldering18Patient ZeroV10Bouldering19Sun BreathingV11Bouldering20Sunshine (sit)V5Bouldering21MoonshineV7Bouldering22Sun PlagueV6-7Bouldering23Black PlagueV5-6Bouldering24Black ShineV4Bouldering25The RampV4Bouldering26Low StansV8-9Bouldering27Stan's TraverseV8Bouldering28SnaturalV7Bouldering29Nats + Stan Mega TraverseV9-10Bouldering30White PlagueV6-7Bouldering31[Redacted]V8Bouldering32LycheesV10Bouldering33Yellow ThumbsV8-Bouldering34Yellow Thumbs SDSV10Bouldering35Stans SunshineV9Bouldering36Full FeverV10Bouldering37New WaveV9Bouldering38The KrakenV10Bouldering39Go Go GadgetV11Bouldering40Inspector GadgetV12Bouldering41Don't Worry, Be SnappyV12Bouldering42MandarinsV10Bouldering43KiwisV12Bouldering44The Impossible TraverseV13Bouldering45Impossible WallV8-9Bouldering46Mission ImpossibleV9Bouldering47Chinese ConnectionV13Bouldering48Egypt AirV9Bouldering49Egypt Air SitV13Bouldering50The OdysseyV9Bouldering51The Odyssey SitV11-12Bouldering52Bench Wall CrackV1Bouldering53Bench WallV2Bouldering54Bench Wall CornerV1Bouldering55EdgesV0Bouldering
