dave,
i did several snowboard tours over the winter to the slides - which i've heard referred to as "angel slides". they are visible as two slides which look like wings from marcy damn, and i believe are the NW aspect of wright.
i can offer you some directions, but would have a hard time giving you a good idea on how much bushwacking is involved during the summer season.
if you are coming from the adk loj, take a R on the trail just prior to crossing the damn bridge. if you are coming from the rangers trail ((forget the name, cross the bridge)). follow a foot trail past (if i remember) either 2 or 3 lean-to's. there are also 3 latrines around this area which may help as bearing points. this trail meanders a bit, but after the lean-tos, transitions into a drainage area. you can basically follow this stream drainage, i would cross it at any opportune time so that you are skiers right, hikers left ascending along the brook/stream. not sure on the mileage, but it should take you about 30-50 min. to access the slide drainage. this will be visible as a logjam of strewn trees. follow that up into the slide basin. from there, you are kinda on your own. i'd estimate that it takes about 30-40 min to ascend the slides, but that is in snowcover, so hard to say how long it will take now.
i will add that the area that breaks up the two slides is quite dense and required pretty tight trailbreaking. this may be the same case anywhere above the slide area towards the summit.
good luck, enjoy.
