Lawn animal damage ?

[bigdog]

I seem to have some lawn damage, just noticed after recent snow melt uncovered the damage. Damage appears to be isolated, close to edge of driveway. Area of damage is about 6'x8'. Trails are raised.....

Is this issue a result of Moles, voles, or some other vermin ?

I did some research on 'voles' and found this description: 'Moles dig for prey, sculpting subterranean housing and highways. Voles travel these tunnels but make their nests above ground. According to Bob Vila, they're more likely to create "runways," channels of chomped grass in service to finding tasty morsels.'

This exactly describes my lawn damage ! Could I have Voles looking for Grubs?

Thoughts ?
