Poison Ivy

Be careful of the poison ivy alongside the trail.  Notice that the leaves come in threes, with an end leaf and two others opposite each other and just behind the end leaf.  The sheen on the leaves is from the oil that can give you a nasty rash.  (That oil is also present in the stems and roots.)  Look at the leaves:  they are not all the same shape, but usually have a gentle wave or two along the edge and no ridge-like veins popping above the leaf surface.  Poison ivy thrives on disturbance; you will seldom find it in the deep woods.  There is more poison ivy on the trail ahead in this highly disturbed area.
