These holes are a result of several mischievous squirrels. Apparently some resident squirrels on this golf course decided that there must be some acorns under the well-kept grass on these golf greens. In an attempt to find some nuts, the squirrels went digging, even though there are no oak trees overhanging this particular green. As you can tell, these squirrels have not been schooled in proper nut-finding techniques or in proper divot repair. After a brief scolding, the squirrels promised never to dig up the green again, although one can never really trust a squirrel.
