Lost Valley Trail is located in the upper Buffalo River wilderness in Ponca Arkansas and is the most popular hiking destination in northwest Arkansas.  This is my favorite spot I had a chance to visit during my Ozarks tree trip this spring.  There are over 700 native plants species found here as well as Ozark chinquapin.  This area has a large number of beech, chinquapin, maple, hickory, and gum trees, and features waterfalls and a cave.  

I found 32 Ozark chinquapin trees along the trail and did not find any sprouts. Most of the trees were small in diameter (3 or 4 inches in circumference) but tall. The leaves were large compared to the leaves I saw on oc south of the AR river.  Most of the trees were in clumps of 4 or 5 and of all the places I went in the Ozarks, the chinquapin trees here were the most healthy and only about 20 percent of the trees I observed had symptoms of blight.
