I think Sambucus racemosa is more likely. The unruly weak branch structure is typical in a woodland setting. The sometimes tree-like shrub almost always has multiple stems from the base. Ash almost always does not. The fruit will be gone, but are in terminal clusters with sambucus, and may still be evident. Ash seeds (completely gone at this time) are born along the stem. http://plants.usda.gov/java/la...
