High atop the Mounds formation, on a blocky section dubbed the Porno Block, is where you'll find this short, southwest-facing route. Approach via slabs from the right (southeast) to reach a spacious ledge system which also accesses the routes Caligula (5.9) the bolted climb immediately right of this route and Deep Throat (5.9) a somewhat novel climb from the old days.
High angle slab climbing with dicey smears, balancy weight-shifts and multiple highsteps is what you'll encounter on the way to the anchors on this route. Though short, this climb has a lot of quality moves and makes a good route to do after warming up on Caligula to the right.
The name comes from a 1972 Mitchell Brothers skin flick featuring Marilyn Chambers (the former Ivory Snow Girl). A nice sunny location, few to no crowds and a relatively short and easy approach make this a route to check out instead of waiting in line (once again) at Echo Rock. Two stars out of five.
