Cinnabar Mines of Central Oregon

Mining in Central Oregon was a booming industry in the early to mid 1900’s.  Though there are a few small gold mines around, the majority of mining was for cinnabar, from which was extracted mercury.  Many of these mines have since been abandoned, their equipment removed and the buildings pulled down.  Most are on private land.  However there are a few with buildings remaining and are accessible to the adventurous as they are presently on public lands. 

The Mother Lode, Independent Mine and The Blue Ridge Mine are all located within easy driving distance of Prineville, Oregon, located in The Ochoco National Forest.


My hubby and I took a trip recently to check some of them out.  We didn’t investigate The Mother Lode Mine, though it is located pretty close to Independent Mine.  We thought we might save that for a day trip completely to itself.  We did, however, find and photograph both Independent and The Blue Ridge Mine locations.  Here are some photos to give you a taste of what you might find if you should wish to see them for yourself.


INDEPENDENT MINE   44.3415231  -120.3527843

Independent Mine is off of USFS (Forest Road) 42 in the Ochoco National Forest.  This is a beautiful drive and has been called the Butterfly Byway, and didn’t disappoint, for they were abundant when we went in early September.  In addition to the riot of butterflies, there are some interesting geologic features along the way.

 Independent Mine is not right off the road.  Take the Baneberry Trail to get started. 


In case you are wondering what baneberries are, there are lots of them at the beginning of the hike.

Baneberries come in both red and white, and both are poisonous.
After a short bit of hiking, you may (depending on the season) need to cross a small creek or two before the buildings begin to emerge from the trees.  The first one we came across was a derelict log cabin.  It isn’t vacant, however, as it seems to be home to a large number of pack-rats.

Old Miner's Cabin


Another miner’s outbuilding.  This one had a jumble of things inside, artfully stuffed with all kinds of plant material that the pack-rats could manage to load inside.

There is an old upended washing machine visible through the window.
As we make our progress through the site, there is another abandoned log structure, nearly overtaken with trees.  One thing is for sure… the people who occupied these buildings were much shorter than their descendants.

Another view of the same log cabin.  Notice how close the window and the gable end of what would have been the roofline are to the ground.

We finally come to the ore processing buildings.

At the upper end of the processing building we can take a peek inside.

 Here is another shot of the upper end of Independent Mine.

Independent Mine was operated from the early 1900’s until it was abandoned sometime in the 1950’s.  It was an open-pit mine, so no mine shafts to fall into.  The buildings remaining appear to have been several residences, a generator building, the remains of the mill, including the furnace.

And the furnace.

We decided to make our way out of the site when we noticed an abundance of bear sign.  In case you are wondering, yes, bears do poop in the woods.
Why did I include this in mine blog post? Because it is pretty.
Back out on USFS42, head east toward Paulina.  There are a few abandoned, collapsed mine sites right off the road before you get to Blue Ridge Mine.  Amity Mine and Number One Mine were both also Cinnabar Mines, but little remains of them now.  If you look sharp, or keep your eyes peeled as my Papa used to say,  you may see the walls of this log cabin fading into the thick stand of trees.  It may have belonged to either one of those long dead mines.

The roof has collapsed in on itself, but the walls are still standing.

When you see the Four Horsemen Hotel, you know you are close to Blue Ridge Mine.  Though some have said that the Four Horsemen was housing for the miners, the son of an early owner of the Blue Ridge Mine claims that the hotel was for the benefit of sawmill workers in the area.

Four Horsemen Hotel - Careful exploring this one, there seems to be a very large active bee colony in the walls of this building.

The first of the mine-site ruins you will probably notice are the rotary kiln and condenser tube foundations.

As you move on up the trail toward the standing buildings, you will first see the concrete surge box with the ore processing buildings behind it.

Blue Ridge Mines date back to 1929, and by 1930 an ore processing plant was erected on the site, and from 1930 to 1932, 250 flasks of mercury were produced.  Shafts were sunk between 1931 and 1941 to a depth of 100 to 110 feet.  In 1942 a 75-ton Gould rotary furnace and condenser system was installed on site and the mine produced 93 flasks of mercury over the next 2 years.  In 1944, the furnace and condenser equipment were removed.  In 1949, a Herreschoff furnace was installed and 129 flasks of mercury were produced up until 1956.  Once again, they removed the mine furnace, this time in 1958, when the mine seems to have mostly been abandoned and gone into decline.  Most of the mercury seems to have been in demand during World War II.
