Open, with restrictions
The original trailhead was closed after someone was electrocuted themselves while playing on the powerlines. Access to the cliff is now gained by parking in a nearby park and hiking through a trailer park. As yet there have been no known incidents as climbers hike through the trailer park however, please be respectful of residents and low key at all times. Please observe any posted no-trespassing signs if they show up.
So far only one established route on this boulder. The downhill face and pretty much the entire top is super loose and pulling big blocks off of this is a bad idea- the slope wants to send your choss trundling into the freeway. Scary to imagine cannonballing a car. Be gentle.
SDS under the small roof at a low left undercling and a right at the pocket above the roof. Mantle the left side of the roof then pull the bulge to top out slightly left. The arete and everything right of it is off but mainly it's still very loose and shouldn't be used yet. Gently downclimb next to the rock pile, there is a ledge that leads to a pretty solid boulder that you can hop off.

Protection and Advice
Pads and a spotter. With the majority of this boulder proving to need cleaning please be mindful of the freeway below. Even smaller boulders will roll down the hill and there isn't much down there keeping shit off the road. This thing would be killer if it was solid.
