i was on boulder glacier not too long ago...we turned around at 7,000 ft not because of the route, but rather the other cameraman forgot the film...oh well...it looke dpretty good though...the trail is wet as hell and the usuall slog through a marsh is still there...have fun...and bring 100% deet...you'll need it... looks like only one main scrund to cross and the rest looks like it will go easily. you could do the ridge variation ...it would probably be easier this late in the season
