Sifting Soil at Lusitania Field
The hopper of an enormous machine is filled with rough soil by a front
loader. The machine then sifts the soil, sending fine topsoil out the
left end, and rocks, sticks, and other debris out the other end. The
sifted soil will be further processed to prepare it for the type of
site on the Reservation where it will be used.
