Digging a hole
Artist Linda Duvall hosted a residency in the summer of 2017 in which participants spent a day or two with Linda in a large hole she had dug on her property. My proposal was as follows:
"I read that Chris Burden once dug a trench for a artist talk, So I would like to hand dig your hole deeper for a day."
I managed to dig down about nine and half feet, and past the glacial layer that covered the prairies about a hundred thousand years ago.
