This is sure to be one of the spookiest parts of The Haunted Mill. You might want to bring an extra change of clothes in case you... well, "soil" yourself.

The owners of The Haunted Mill have added, what I believe to be, the most disturbing and claustrophobic attraction yet. This would be the 300-foot underground mine that legend has named the Miller’s Mine.

The Miller Party was one of the first groups to cross Idaho on the Oregon Trail. The company of seven families was named after the Albert Miller family, who funded and led the expedition. The Miller Party was headed to Oregon in search of land to make into a homestead.

The Miller Party would be crossing Idaho in the fall of 1855, during the Idaho Gold rush. Most of the miners were paranoid of others laying stake to their claims. One group in particular was convinced there was gold in the area that is now called Teton. The years these miners spent searching for gold drove them mad. When they saw the Miller Party crossing through their area, the miners didn’t think twice before they slaughtered every man, woman, and child.

After the slaughter, they piled all the bodies and belongings of the Miller Party on a nearby hill and burnt them until they were no more than cinder and ashes. The miners feared that, if they left the bodies to rot on the land, the smell would attract mountain lions and bears.

After a long cold winter, spring came, and the miners decided they should dig a new mine. They were still convinced that there was gold somewhere in the region, they just neglected to dig in the right places. As they were searching for a new place to dig, they came across the site where they had burned the bodies of the Miller Party. The hard winter and gold fever had blocked the slaughter, and most all of their other memories, out of their minds. They only thought about the gold. As they crossed the site, they noticed something. It was gold. Not a lot of gold; fourteen small lumps of gold in total. They thought for sure all of their years of searching had paid off and the gold they had been searching for was buried in the ground beneath the hill.

One by one the miners who were digging the mine began to disappear. Convinced there was gold in that hill, the others were not bothered by the disappearance of their comrades. Actually, many of them were secretly glad, one less person to split the gold with. Eventually, all the miners disappeared. The families the miners left behind began to worry when they had not heard from their loved ones. A search party was formed to find the missing miners. When they arrived, they did not find any of the miners at the mine and the campsite looked abandoned.

Instead, at the entrance of the mine, they found a journal and fourteen small pieces of gold. Hoping that the journal would tell them where to look for their loved ones, the search party opened the journal to the day that was marked, October 15th, or the day the miners massacred the Miller Party.

The journal entry, written with what appeared to be the sharp tip of a cinder, contained a history of what had happened to the Miller Party, the name of each person that was killed, and a plea to bury the remains of the wedding rings that belonged to the parents of each of the seven families (the fourteen gold pieces the miners found) in order to put the souls of these families to rest. The entry was concluded with one eerie remark:

"Get the job done quickly. The mountain lions, which have chosen the mine as their den, have developed a taste for human blood. - Albert Miller Leader of the Miller Party"
