unknown insect burrow - Geolycosa
Bend, Oregon, Deschutes County, Oregon, USA
October 15, 2011
These "burrows" are all over the desert East of Bend. It's Juniper/sagebrush country with generally sandy soils. I was thinking it might be a ground nesting wasp, but am not sure. Any help in identification is much appreciated.

I think this is an interesting shot. I cropped out the ruler, which showed that the ring of excavated material is about 2.5 inches across.

Wolf spider burrow
Identifiable by the turret, incorporating bits of vegetation, that surrounds the entrance. If you picked apart some of the excavated material I think you would find that those little balls of sand are held together with silk, which would not be the case with an insect burrow. Ground-nesting wasps typically have a slanted burrow entrance, rather than straight down like this, and pile the excavated material to one side rather than in a ring around the burrow.
