Looking at your picture and googling I can't seem to find a match. Let me give you some precautions though. As a tennager, I earned money by catching water mocosins and copper heads in Misissippi. I sold them to a hospital for them to milk and create anti-venon. Horse blood really. The precautions are :
1. triangular shaped head means poisonous.
2. Your picture shows a very small snake probably new born. Snakes normally give birth to 20 to 30 snakes at a time. So the area you found it has plenty more.
3. Size and age are no indication of the potency of their venon. A new born could kill a human.
4. If there are babies there must be adults that created them in the area.
Please be cautious. Wear working boots at least.
