Since the Marble Mountain route doesn't appear to be workable, would something like this be a good alternative? http://www.fs.fed.us/gpnf/recreation...riptions.shtml or is it too far/too tame/too crowded or too something else I haven't considered? I may be able to free up some time on the 29th or 30th and go check it out, assuming the rainy season is not in full swing by then.
