it  was  a  burial  ground, the  grave  was  dug, the  pit   near  the   feet  side  was  deeper  by  three feet, covered  with  a  wooden plank, to  hide  it  from  view, the  plank  was  covered  with  dry  grass  twigs and  other  wild  foliage, the  ones  who  wanted  to  hide  the  tunnel  must  be   arriving  to  dig  it   longer   after  dusk  and  left  before  dawn
