But as severe drought spreads across the Midwest and pushes river levels to near-record lows, people can now reach the rock formation on foot.“The river has dropped low enough that you can walk over to Tower Rock and not get your feet wet or muddy,” Missouri resident Jeff Biget told CNN.“I only remember being able to do this one other time in my life.”Photos taken by Biget show people hiking across the rocky river bed to the island tower – a trek that poses little risk in the near-term as water levels are expected to continue to drop for at least the next two weeks.Tower Rock can be reached on foot when the water level is below 1.5 feet at the Chester, Illinois, river gauge, according to the Missouri Department of Conservation.“We’re not loading right now.”Gilbert said that instead of shipping their harvests right now, many farmers are “just throwing it in their bins” and waiting for better conditions, which could still be weeks away."
