fyi,
this is second hand info, but I know some folks climbed the Adams glacier over memorial day weekend and rather than starting from Killen Creek, they drove north on Rd 23 from Trout Lake as close to Adams as they coudl get then hiked cross-country (relatively open forest, no bushwacking) to treeline on the north side of Adams...they wrote that it added an extra mile or mile and a half to the usual killen creek approach.
please post a TR if ya go...I'm hoping to head in there later this month.
