This isn't a very hard cache. The cache itself is very large but the object to open it that is placed at the listed coordinates is quite small. You are looking for a small black tube. The lid is a bit tight but it will come off.
Watch out for ants.
To get to the listed coordinates follow the road until you are directly next to it.
