I didn't think why this particular one was so interesting to me when I first took the picture (apart from it's unusual angle and inverted conical shape), but the more I thought about it, I realized that it seems to me to be an almost perfect negative version of a hole which has been covered by its' maker.
The 'door' of these holes is usually closed by a pyramidal shaped pile of dirt (the dirt which was used to create the hole in the first place), and this strikes me as a sort of inverted version of it, not literally an exact opposite, but a kind of allusion to it. It works abstractly in a way that I find uncommon in art made by human beings.
Although it is difficult to tell this in the picture below, the hole is dug in a way that the gopher that made it appears to have had it's angles askew, perhaps searching for the top of the ground, but taking a couple of wrong turns along the way. While I am a person that usually thrives on rational ways of doing things because it provides a sense of order to my sometimes chaotic-feeling inner life, I find that unusual turns and obtuse choices makes the world more interesting and life worth living.
