They do not dig
deeply because they are excavating just under turf

Wrong again ratbreath. Mole nesting chambers tend to be 12-18 inches deep.
They dig two types of tunnels, those just under the surface for feeding and
interconnecting tunnels 6 to 20 inches deep for travel between feeding and
nesting areas. You need to check your facts prior to posting.
