Its early spring now and I just noticed hundreds of little dirt piles all over out back yard. Each pile has a small hole in the center of it and sometimes is about 2 inches tall or so and about and inch to 2 inches wide.

Hello,
The piles are earthworm castings(excrement), little piles of poop left after the earthworm goes back into its hole in the ground. The larger pile could be a group of them located in one area or a mole hill left by a mole coming to the surface to eat the worms.
