This is the tri-summited dome seen to the east of Stateline, South Tahoe It lies to the north of Kingsbury Grade. There hasn't been much done here. A few routes in the 1970s. I top roped some stuff in the 80s but never recorded it. Now a small sport area has been established. The rock is volcanic and not of high quality.
Take Kingsbury Grade to North Benjamin. Head north. Benjamin becomes Andrea. Take this to where it becomes dirt. Follow this to another road heading west. Park near a meadow and walk about 100 yards north.
I just made a pdf of the original topo from about 1992 or 93. It was 6 pages stapled together. Chris Dornsife and Dave (can't remember his last name) put all the bolted stuff up there. I remember they were short but pretty fun.
I haven't been up there since 1993, so I have no idea what condition these routes are in or if the bolts even exist anymore.
The roads in that pdf have long since been decommissioned and turned into trails. Park at the lowest part of the large parking lot before the road turns to dirt, hike about a mile, and you hit Castle Rock. There is one fork in the trail with an obvious sign to Castle Rock.
Lots of chossy but cool rock up there. Could rival Luther Spires for mellow sport climbing if someone had the motivation. Good bouldering too it you feel like humping a pad for a mile.
i found the pdf hard to decipher so I put together a little map from Google maps satellite view. Checked out camelot recently and found the anchors at the top (2 sets) but couldn't see any bolts below. It may be a trad route or it may just be runout at the top since it's not steep there. I highly doubt it's topropable but is probably single pitch leading and easy to walk off. Never looked at it from below though
