beneath my feet as I climbed the hill to my favorite spot. I was eager to begin the search for fissures containing quartz crystals. It had only snowed about two inches last night so I knew the snow wasn't going to be a problem. A few shovels and I'd be back in business. My friend and rockhound Bob Crocker showed me this place back when I first got serious with this hobby. I am indebted to him because of the places he has taken me, not to mention how my collection has grown as a result. So I dedicate this trip report to Bob Crocker. Thanks Bob. |

earth away until I reveal quartz or I hear a loud crunch as the mattock finds it way into a fissure. Obviously I prefer the former case when finding the fissures, but if I were to be too cautious I might spend hours carefully pecking away at the dirt only to remove a few inches of dirt and then only to find myself at the days end without a specimen to show for it. The fissures in this area tend to be around one foot or less in length and only about one to two inches thick. Fissures larger than that are very rare, and when I do find those I am very happy to say the least. Once I have located a fissure I will switch to smaller tools to prevent damage to potential specimens. As expected my spot was covered with snow (above). |

are in the photo (above). The mattock finds its way to the fissures quickly and the smaller shovel is used to maticulously extract the goodies. Since the shovel is metal I am always careful to dig at least a couple inches beyond the edge of the fissure walls such as not to damage any of the specimens. |

Many of these fissures have roots growing thrrough them. The fissures are paths of least resistence for roots growth and so it is common to find them filled with roots -- as can be seen in the photo above. |

from the mechanical weathering of frost thaw action that many of them fall apart after extracting them from the clay. And this one did just that. (above) |

pile of tailings in the bottom of the pit. I was just about to scoop it out of the pit before seeing it on the tip of my shovel. It apparantly fell out of a fissure at some point. Although I am pretty meticulous when I dig I am always reminded when this sort of thing happens that it's unreasonable to think I can possibly catch everything. |

hours with only one quartz crystal to show for it. So I took a small rest and decided to take just a few more swings with my mattock to the pit walls. Pulling away the earth revealed this black shape in the clay. My heart jumped as I immediately recognized it as a crystal face. Crystals appear black when they are embedded in the ground because they capture the ambient light and trap it inside. |

The surfaces of the crystal where the layer of iron oxide was thickest were frosted or etched. This was the crystal in my hand on the left side of the previous photo. |

I realized that the size and shape of contact area on the tabular crystal was very similar to the contact area on the largest crystal I pulled from the fissure. |
|
crystals were separated by inches of clay. There must have been considerable ground movement after their formation so that they all lay separate in the fissure bottom. |
