I get holes like that too.
Central New Jersey.

My best guess is Skunk.
Looks to me like an animal digging for grubs.

Clue #1: Where's the dirt that came out of the hole? A squirrel,
chipmonk, or other top dwellers would leave the dirt near the hole. A
snake will move loose surface dirt to get under something (i.e. a
mostly horizontal hole) but they're not going to dig a verticle hole
out in the open like that one in the pic.

Snakes have no means of digging. They may use holes dug by others but there
are no snake excavators.

Chipmunks make nice clean holes like that and they lead to
chambers and other exit holes.

I have holes just like in the picture.
They go down about 2 inches with no tunnels going anywhere.

We have lots of chipmunks but I'm outside all summer and I've never
observed one being dug.

We have other holes that are plainly chipmunk tunnels.
Almost always next to a root or rock so they can tunnel under something
solid.

We have lots of raccoons and skunks. So since I don't see them in
action, I blame one of them.

Looks like a vole hole to me... they're critters similar to mice, and they tend
to make these flat holes that are (depending on species) 1-2" or so.
Other possibilities include crawdads and chipmunks, as well as a number of
other species. Depends on where you live, but a call to the local extension
service or master gardeners will usually get you a list of local probabilities.

Gophers typically dig a mound with the hole off to one side and a fan of
bare, dug up soil around it... sort of like an off-center egg yolk in a fried
egg. Moles make volcanoes with the hole in the middle. Voles do the very
flat holes, usually 1-maybe 2" in diameter, depending on species and local
erosion.

Voles are also known as meadow mice or field mice, and look pretty mouse-ish.
Short ears. They go through boom and bust population cycles
(like most small mammals) and you're probably in a boom year now... about
7 years is a typical small mammal boom and bust cycle. You'll probably have
a lot of happy owls, coyotes, cats, etc. with full bellies. <g>

If you see a lot of plantings that look like you've got root disturbance going
on, pull any loose mulch away from them and you'll probably get the voles to
go elsewhere.

Look at other posts in this group about getting grass to grow. You'll
usually see a response about renting an aerator to make holes similar
to the ones you have. It allows air to reach down into the soil and
makes plants healthy. So if the holes you have are not causing you a
problem consider them a benefit.

Aerators make holes about 1/2 inch in diameter. The original message in
this thread indicated holes about 2 inches in diameter, which can be a
hazard to an unwary person walking across the lawn.

And if voles they are far more destructive than moles... mole
tunneling is merely unsightly but they do the benefit of eating
grubs... however voles eat plant roots leaving death in their wake.
The reason there's no mound of excavated earth at those holes is
because they are very likely exit holes, their entrance holes could be
many yards away, maybe under a large rock or shrub. If you begin to
notice dying plants and dead patches of lawn you have voles. I didn't
notice any lawn around those holes, just bare earth and sparse weeds,
very likely not a gardener living there, just someone curious about
the holes but in all likelyhood will do nothing about them.
