Bark looks very much like black cherry. See if you can find cherry pits on the ground (very small for wild cherry). Dried leaves are serrated oval with rust colored hairs on underside along the stem at base of leaf.
at first i thought it was cherry.....was it on the ground long? the bark is not quite right for cherry. we do not have hickory here so i have no advice on that one. use google image search and look for cherry, black hickory bark and look at the pix.
Sorry Neens, I may have spoken out of turn. What we have here is the Colorado State University Extension Service. They have several divisions, including horticulture. I guess I wasn't thinking when I mentioned it to you. Sorry! Keith
that one does look a lot morel like apple.....simple test....grill a few burgers and toss some on the coals......if it tastes good, GREAT!......if not....you're not out the price of a boston butt......:D
Looks like cherry to me. I hate to be that guy but there is a wide range of answers. I would hesitate to cook with it until you really identify it. As long as it is an american hardwood you should be in the clear. I does not look at all like a needle bearing tree so you should be ok.
If you want to find out 100% fo sure what kind of wood it is before you use it . Look in your phone book for a sawmill close by and take a chunk of it and they'll be able to tell you what it is with out a doubt.
