I wanted to try attaching the images within the email (instead of linking), so fingers crossed that they will post correctly... The last image is for scale; the gardening carriers the cluster is sitting in has 3 ft. circumference (I hope that's helpful!)

well that is wild! Crazy how the crystals all grew willy nilly in random directions.
Great find.

Those are some unusually large crystals you are finding.  Well done!  Great to see someone else checking construction sites for crystals as there is always so much opportunity.  Have you been able to find the source veins for these crystals or are you finding these randomly on the surface?

thank you! Scott, I don't think I've found the source (if there is one), and frankly, I don't know how! I have done a little bit of digging (when I see something interesting poking up on the surface), but I'd like to dig around a lot more. They are going to put up a house there very soon, and I'm sad to think what will be covered up!

If anyone would like to dig there, I would be happy to share the location, and, if you're willing, I would especially like to join you so that I can learn 

You are right, there's a some great diversity going on there.  I see garnet, mica, and both smoky and clear included quartz.  The pyramidal mineral is possibly magnetite. It looks like potentially hematite or rutile included in that last piece of quartz.  Great pictures by the way.

Most large construction sites prefer that no one enters the property if they could help it. If possible you can ask workers permission to look for rocks, but many times their hands are tied and in order to not risk their jobs they must say no. That is why we search on Sundays.  There will be no workers driving heavy machinery that have the chance of injuring you. Unless there are "No trespassing" signs posted, in which case it's off limits, than it's much easier to ask forgiveness than permission assuming someone does confront you. I am pretty much never confronted, and when I have been they were perfectly fine with what I was doing when I explained. There has only ever been two places I have been where they didn't care what I was doing but didn't want me there because of liability issues. Be safe, be smart, and stay away from deep or high embankments, do not go underneath or near buildings under construction where things can fall on you, and surface collect only.

that is good to know, Scott, and I never thought about their being 'rules' for property under demolition (in other words, as long as there was no building going on, I didn't think it would be a problem).

But the site I've been going to, I was able to meet the real estate/broker/owner, and I did ask his permission to poke around (he didn't mind at all). I mentioned that if I arrived and found anyone working in the site, I would stay out of their way. Also, over the past few months, I was able to meet one of the surveyor and other guys involved, and I would explain to them what I was doing. The surveyor was able to tell me some of the history of the site, which was really nice to find out why they were doing what they were doing with regards to grading and moving earth around. They really didn't care that I was digging for rocks; in fact, I guess you could say I was doing them a favor by taking away rocks they'd have to remove anyway.... ha!
