The cache is a .50 caliber ammo can.
Between and under some rocks.
In the winter time there can be several feet of snow.

I own the land (which has been in the family since 1916) so don't worry about trespassing. Just don't drive your vehicle through the field.
Watch out for uneven ground because it's easy to sprain an ankle if you aren't careful.
