i want to bring in now randall orndorff. he's a geologist with the u.s.talk a little bit about the sinkhole in this house. first off, do you think, randall, that we'll be able to get a sense of what it looks like once this demolition is done? i know it's going to be a long process that will probably stretch into tomorrow sounds like. >> sounds like they have a good idea of how large the sinkhole is length and maybe depth wise. if they get better access to it, we'll be able to see more. also maybe understand its shape, give you a better understanding of if it grows in other directions, if it will grow toward those other houses. >> when you say understand its shape, would it be something besides a circle? >> well, depending. it's probably circular. could be oval. one direction could be longer than another
