Post up your pics here if you've been lucky enough to stumble across any. I have several specimens (none are from the Lykins Formation). All of my finds are from Grand County and at a fairly high elevation in relation to the Lykins Formation. I believe they were encased and preserved by a volcanic event. As the volcanic surface rock (extrusive igneous) erodes they are exposed. My finds have been loose alluvial... or placer in nature, just keeping my eyes peeled and flipping rocks.
This is probably my favorite. It has a bonus.... a druzy pocket on top that is filled with micro crystals. This one probably got pretty hot. Fossil/gem or geode combo I reckon. Kinda ugly but kinda purty.... hey, it has inner beauty.
