This rapid is on far river left below Gabriel's Bend. It is scrapy below about 2,000 cfs.
This channel is rarely run because it joins back with the river below the takeout, requiring a paddle back upstream. That's a shame because this channel has an intimate, almost Nantahala kind of feel. The beginning of this channel has the namesake Tombstone rock. After that the river runs through a series of Class II rapids until you hit the dreaded lake that has buried many legendary rapids. During the recent drought, there were a couple of extra rapids in this channel, one with a nice surfing wave (before I could roll, much less surf!). If you go down this channel, stay to the right after you hit the lake. Once it merges into a single channel, take a right and paddle back up about 0.2 mile to the takeout.
