Good eye finding those crystals.  It is a very tricky thing to chase the origin of crystals in a creek or stream.  Although a fissure containing buckets of crystals may be very near it is difficult to know how far those specimens have traveled from years of water flow.  You'll have to find areas of the bank that are in-situ and not sedimental deposits.  Depending on where you are it may be impossible without some major digging.  But in areas where the banks are clearly in-situ this is where you should be concentrating in order to find fissures with crystals.  Even then it can be difficult as all fissures are not created equal and sometimes are disguised in plain view.  But, keep positive and keep looking, you'll eventually find something real nice!  Good work.

Collin,

As Scott stated and based on your pictures, everything i see is an alluvial deposit, in fact its almost identical to another creek/area that most of us on here know about and have dug and i suspect the spot you found is in the same area. The dark gray layer would be the best bet for crystals, but again, not the original source, it's likely further upstream, and perhaps even eroded and gone.

I work nearby Centennial, perhaps I can sneak out of work early one day soon and meet up with you and we can do some sleuthing around. Daylight is the problem now, it gets much easier in spring/summer for those after work hunts.

Yes I know the pics are bad, I was in a rush/crystal frenzy and couldn't keep my hand still enough to take good pics   

Tim and Dave, I appreciate your replies!  I am very excited to return to my new spot, however, with the sun going down at 5:30 it will be hard to get out there after work. 

Hopefully in the next few weeks I will be finding some cool stuff from that spot.  It appears that it used to be a pond a long time ago and dried up in the early 2000's, so maybe it is older than I thought it was.  The creek looks to be the lowest point of the pond and has been there since it has dried up.

Dave I will shoot you a pm and would defiantly like slueth around sometime, I can show you some of my prospecting spots.  I live almost right on centennial campus.

Thanks!

Fixed this picture as well.  Sorry about flooding the topic with huge pics! 

Hi Scott,
Thanks!  I have not looked too close at the specimens for rutile yet.  I did notice that this is very very close to somewhere you have posted on this board that you found some rutile.  Hopefully I will find some!

Thanks Scott, I will take a closer look at them.  I believe there is some rutile on them.  I'll bring my collection to the meeting on Tuesday.  Here are 2 more I found the other day, I think i found a good smokey spot that I am returning to on Saturday
