St Peters Dome Fluorite

I have been wanting to visit the St. Peter’s Dome fluorite locale for a while as I heard the fluorite was beautiful and plentiful.  Friends Matt, David and I visited the location and it didn’t disappoint.

The location is accessible by a normal vehicle along the Old Stage Road where it meets Gold Camp Road coming out of Colorado Springs.  If one is unsure of the last road to the mine, they can park at the St. Peter’s Dome parking area and walk the 200 yards to the mine dumps.

Fluorite is everywhere.

Purple, green and white fluorite litter the ground.

There is a bunch of fluorite laying everywhere, mostly in small chunks.  You can take a sledge and chisel and work some of the larger pieces if you so chose, but I just walked around and picked up a dozen or two smaller stones that looked like they had interesting color or marbling.  

I have a flat lap so I took these stones and polished with a 150 lap.  They look really nice all polished up (wet in this case), so I will continue to shape and then polish the stones.

  1. These should polish up pretty well as I believe they have some silica in them. The fluorite from this location should be thermolumescent so try heating up some of them up in the fire and watch them glow in the dark! Unfortunately they do not appear to be fluorescent in lw or sw.

    While the fluorite here is massive, supposedly you can find crystallized faces with a bit of luck. You can see that in your last photo with the triangle pattern locked inside the massive material.

    Too bad you didn’t get the chance to explore Eureka Tunnel which is far down the slope from the main parking area. Nice small gemmy zircon and some rare minerals can be found inside.

    The first time I tried to find the tunnel, I collected at that fluorite slope and went the wrong direction down a side road. Did find some mine shaft dumps but there was still a bit of snow on the ground. Did collect some large crude quartz crystals in a talus slope next to the side road. Also some cleaved fluorite crystals were found in that slope. The second time I went with someone who knew where the tunnel was. The tunnel is very hard to see until you are almost on top of it.
