Thorium and rare-earth rich rocks from the Lemhi Pass near the border of present-day Idaho/Montana. The first picture of the reddish rock is from the Last Chance vein and features approximately 1:1 ratio of thorium:rare-earths. The second picture is a piece of carbonatite from this area which features a 1:12 ratio of thorium:rare-earths. The third picture is mostly of rocks from the Lucky Horseshoe vein from this area which I personally visited. The ricks in that vein have a 1:6 ratio of thorium:rare-earths.
These pictures are mostly for display purposes, although I might be able to sell some rocks to someone who might be interested in them for health or novelty purposes.
