The most recently dug strip of ther allotment is having tunnels constructed

Could be a mole, but no mole hills and I thought moles went deeper.

They dig in that way when hunting worms, and throw up hills only
when they need to get rid of the spoil. If they are digging just
below the surface, they don't need to.
