shows the Berkeley Pit from the viewing area in Butte. You can
get a good idea of how much digging has been done in and around
the Berkeley Pit in this photograph. In case you're wondering,
the lake you see before you is more than 1800 feet deep! And
water is extremely hazardous to your health - so don't drink
or swim in it.
Pit has been filling up with water ever since the former owner
of it, Arco, stopped pumping out
the water. Ever since, it has been filling up with water at
a rate of 6 million gallons per day (recently slowed down to
million gallons per day due to the stoppage of water intake
from another nearby active strip mine).
