The river was bone dry for most of this section, something that isn't rare this time of year for this part. In fact, the water is there, it is just flowing underground through the karst and it resurfaces downstream in interesting springs. Oddly enough, we had to cross flowing water at Woolum, but then were able to cross the dry bed downstream of there to camp near Dave Mane's Bluff and Ben Branch.
We heard tons of coyotes at night and saw a lot of stars.
Here is a link to more photos of the dry river bed: http://trailsofarkansas.blogspot.com/2012/08/buffalo-river-low.html
There are some interesting trails near here up around Point Peter:
