Thanks for the specie names. I had fun searching out info. I still cant decide what kind it is but heres an interesting document on two different types of Geolycosa that indicates spider size may be calculated by burrow size, plus other interesting info.

I've seen much bigger burrows and maybe over the summer I will get some better shots.

Thanks again for the clues!

also, as time goes on its turret, if any, will be interesting
and usually this genus can be found in numbers
close by, so look for many holes and different sizes
to help define year class and gender.
