This is a mound of dry, unconsolidated soil pushed out and up through a circular hole entrance. The artist is a Botta's Pocket Gopher living in the Blue Oak Savannah of the central Sierra Nevada foothills.
What I find interesting about it is that structures at radically different scales on disparate worlds can be made by similar processes, even in a back yard.
While there are better analogs at closer scales (Inyo Domes for example) this is essentially the same process, admittedly at a lower temperature.
Love, just seeing this. Hilarious and true observation. ❤ LMReplyDelete
