I love this one, and the following picture too... and I had never heard of Rhyolite (assume it's named after a mineral?) so thanks for describing it, picturing it & explaining it's (limited) history!
I love these, too. Nice and creepy, the way I love my art heh heh. I like how you got the backdrop in there, too. Adds to the desolation and makes the white of the statue stand out.
This is my favorite of the group, however many are haunting.
