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
