Gopher or mole (without seeing the animal)?

There are three clues to look for when trying to distinguish mole (Scalopus) sign from gopher (Geomys) sign.

  1. Texture of soil in the mound:
    very lumpy = mole (https://www.inaturalist.org/observations/13015309)
    granular (and sometimes with a plug visible) = gopher (https://www.inaturalist.org/observations/5087818)

  2. Position of mounds (not always apparent):
    no directional pattern or rarely distinctly curved = mole
    several in a fairly straight line = gopher (https://www.inaturalist.org/observations/4550501)

  3. Depth of tunnel:
    only an inch or two = mole (https://www.inaturalist.org/observations/1242426)
    over a foot = gopher
