| |
|
| San Juan Co., Longfellow mine |
 |
| |
Enough faces on the crystal to qualifiy it as a crystal, ugly as it is. Milky white thick crystal fragment, 2x3.5. Perhaps there was more when the mine was active. This was personally collected and in a place right at the mine where it could not have come from somewhere else. |

|
| San Juan Co., Silver Lake Basin, "Round Mountain" area |
 |
| |
Tiny thick barite blades, to 0.4 cm wide, equant, snow white rims, milky centers, perched on quartz needles to 1 cm with glossy transparent light amethyst tips, all in thick group. 4.5x4 cm. Collected by Benjy Kuehling from area in the basin known locally as Round Mountain. |

|
| San Juan Co., Sunnyside mine |

Must be very rare from the Sunnyside, but see Dave Bunk's white barite blades on nice pink rhodochrosite, 2.8 cm wide, on page 75 of Lithographie's No. 15 issue "The San Juan Triangle of Colorado-Mountains of Minerals," 2011. |

|
| Weld Co., Stoneham (some evidently nearer Raymer, or in Logan Co.) |
    |
| |
These fairly gemmy, lustrous light blue crystals are 7 cm tall and as is common, with small light yellow calcite crystals. The small very clear crystal about 3.5 cm tall. The two darker crystals, virtually no damage, do not have bright luster, but really are about this color, and are 8.5 cm long, each. Very translucent/transparent doubly terminated crystal, 8.5x1.2 cm, frosted "pyramid" edges, other faces pretty glossy. Three smaller crystals stick out like arms to the sides from the same location, from 3 cm to 1.2 cm. Very thin. |
