The shot took place in Area 51, 8050 pit, at <br />proximately 10:40 am between two of our approved shooting times. It was <br />detonated out of time due to wet hole conditions causing loaded holes to sink. <br />Once these holes have sunk, risk of misfired holes will increase, which <br />decreases blasting safety. <br />Sincere , <br />;~ . ~~ <br />Richard J.
