Crux is a slight roof you have to pull which is a loose block which is kinda scary till you hit 'ok' crack climbing. Grade III for alpine environment.
passing M2 spire coming through the saddle of the pass created by the enormous choss pile you will find a cool bulbous rock structure. Looking at the west face it is the short (guide says 20m) structure to the right of El Abuelo
From one aspect you can see purple/blue webbing. This is the rap anchor for the climb. Climb is on the west face of this mini spire. Start at a low ramp and trend up and left following a crack system.
Insecure for 5.6, lots of loose CRAP rock towards the bottom and that's what's your pro is in. Avoid it because there are WAY better climbs at Frey.
