Noice! Tourmalinated quartz rules! I like the one with the verticle vein running thru it too! I wonder what that vein is? Like a clay inclusion or something?

NICE! I like the tourmalinated ones. Thanks. There is actually only one (front and back pics, forgot to mention that). |

Never know what you will find around here because of the glaciers. |

They all look great for creek rocks. You must really get a lot of water though that creek to move them around and expose new material. You did a great job on polishing them. Wondering about the shape of the rocks when you picked them up, were they well rounded to start with. I’ve hunted creek beds for rocks targeting the rounds think I might get lucky with a super cool one , not yet but could happen. Nice job Chris1956 thanks for sharing

I took a closer look at it under the loupe today. I originally thought it was probably just colored quartz. However, it is slightly undercut so I am not sure what it is. |

Two good questions quartzilla. Here in northwest Missouri, we often get very intense thunderstorms. The intensity of the rainfall can be absolutley amazing (plus being in farmland can mean you get more instense runoff also). Much more intense than where I grew up in Michigan. Consequently the creek channels are huge but typically have little flow in them (all the better for picking rocks  ). Below is a picture of the "creek" under pretty normal conditions (just a trickle of water). The creek often goes surface dry during the summer and fall. Hard to see from the photo but the channel on our property ranges from 6 to 10 feet deep and 20 to 30 feet wide. It probably comes close to filling that channel up 2 or 3 times in a normal year. It depends on how wet the soil is as to how big and fast a rainfall fills it up. Generally something in the 3 to 4 inch range in 12 hours will fill it up.  Three years ago, we got 10 inches overnight. The first picture below shows my hay pasture under water (creek is to the left by the trees). The hay pasture ground is level with the top of the channel. Second photo was taken from the road and creek is at the trees. So water in the channel was probably in the 10 to 13 feet deep range. I found lots of rocks after that rain but had to wait a few weeks for the water to get back down to a trickle.   You asked about the shape of the rocks that I pick up. I didn't have any unpolished quartz ones at the moment but here are a few pics of quartzite. You can see that there are a few that are round. I would say that the actual quartz is less rounded than the quartzite. I think it tends to break along the crystal planes and probably gets more roughly broken as it rolls down the creek (compared to the quartzite that probably breaks between little grains). The hard part is that most of the rocks are covered in dried black/brown algae/slime growth and it is hard to tell what they are.    Chris |

Wow loved the pictures looks like a great place to find material. Dry creek beds and wash outs provide interesting finds now and again depending on the erosion. I have found some cool stuff not outstanding but cool. Thx for sharing

No need to apologize, I’ve been enjoying this thread and and find all of this of interest. Really great to see how all of us in different areas/climates/geological differences find the stuff we work with! |

You have a lot of variety of nice stones in that creek. No telling what minerals you may find if you keep looking.

You have a lot of variety of nice stones in that creek. No telling what minerals you may find if you keep looking. Well that inspired me to try to make a list of everything I have found in the creek (and two adjoining properties with continuation of the same creek) that has been of interest for polishing. So here is my best recollection at the moment. All of these are glacial I think except for the local banded chert. Although I keep thinking that what I think is brown jasper might be local and maybe is brownish chert because most of it looks like it hasn't been tumbling around in the creek for long. I will have to investigate that some more. Of coarse the good stuff (agates, petrified wood etc) is in small quantities. Banded chert Lake Superior agates Petrified wood Slag/obsidian - Still not sure what this is but have found additional small pieces in the creek (both black and a brown color). The brown shows conchoidal fracturing. Red jasper Brown jasper Black jasper (solid, not like the slag/obsidian) Best guess anyway Green jasper - only once Copal/amber - only once Quartz Quartzite Chalcedony - most of this is a translucent greenish/grayish variety. Polishes nicely. I think this might be something that could possibly come from the local limestone but not sure. I do occasionally find small chert nodules in the limestone that are translucent and show conchodial frracturing. |

Nice polish Chris. I have a bittersweet relationship with Quartz.
I've let it down more than once lol
