Is anyone keeping up with this tunnel from a geological perspective? At 85 feet deep and ~20 feet in diameter, I wonder about the rock there and if they are likely to hit any caves. I also wonder if they know whether or not they will hit any caves and what could possibly happen if they do so. Is there any typical features of caves that exist that close to the Colorado River? Is such a cave likely in this area?
