We weren't able to get it out of the canyon, but we did pull it out of the river. Extracting the boat on foot would be a long day. You'd probably have to walk down from the put in for USB along the train tracks on river right. The boat is about a quarter mile below LZ on river right at the bottom of a scree field. There is no way to get it out downstream. If you decide to go get it, be careful walking along the tracks. Besides the potential access issues, there is alot of train activity on the tracks, and surprisingly, those big locomotives can sneak up on you pretty fast, so just be heads up.
