i would say that all those climbs are not really suited for a large group of beginners. small ledges, natural anchors and long lines will affect yours and everyones elses enjoyment of the day.
after the 1st belay ledge on nutcracker they get smaller and smaller...more then 2-3 people makes them awkward and potentially dangerous from crowding.
have fun...we are getting pounded by the snow for the next week or so.
muginella has considerable rockfall potential from climbers and hikers above.
the grack is located on glacier point apron. spring is a bad time to be on the apron as spring melt increases extreme rockfall hazard.
