Iroquis Mine was one of few very recent mines to be opened (1949) for exploration
purposes, and they had hit on a large seam of datolites that they mined
and dumped on the mine dumps. Almost all of the datolites found there are
white, and some includes orange to pink dots. The mine dump had been bulldozed
from time to time. I advise against bringing any metal detectors to the
mine dumps for the dumps are very rich in the prehnite rocks with bits
of copper.
"Snowman" datolite with rare orange dots
"Mittens" Datolite, largest datolite I have found so far.
