Aggregate Piles - Great
dive site in Lake Mead! This is the Gravel Screening Plant used in the building of
Hoover Dam. River rock was extracted from dry beds over on
the Arizona side of the river, transported by rail to this area,
sorted into 4 different piles based on size, washed with water
that was de-silted in the "batch plant", and then transported
again by rail to the dam site where it was mixed with cement and poured.
These piles are huge - You just can't get a feel for their size
until you drop down on them.
This area has been under water since 1936, but is now within
recreational dive depth, yet has
only been seen by a relatively small number of divers.
If you
visit the Aggregate Piles, please respect that they have
historical significance, and do not damage, destroy, take
objects, or leave
your mark in any way.

Note how these massive piles
dwarf the building and vehicle. |
