As noted in Bob R's report <A href="http://www.whitneyportalstore.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=1;t=003203">Mt. Whitney via the Trail, June 19/20</A> people have not using the switchbacks because there is still a lot of snow between about switchback 45 and switchback 50 and there is an alternative route up the snow slope. As a result, the snow is not getting trampled on and the ice is not getting chopped up in the switchbacks. Until we get some reports of some pioneers going up the switchbacks, we can only assume that they are not safe for people without the proper equipment. Please be patient. Hopefully, we will hear more from trips up this weekend.
