Apparently the chaddar is in condition early this year, Zanskaris were traveling on the frozen river before Losar (17th December), although of course by now conditions may have changed.

I've just received an email from a friend in Zanskar, Sonam 'Jimmy' Stobgais, one of the most experienced frozen river guides. Jimmy is free this year so if there is anyone thinking of dashing out in the next few weeks to embark on one of our planet's most rewarding treks, contact Jimmy to organise your chaddar/frozen Zanskar river trek. Jimmy's contact details can be found on the trekzanskar site.
