So on our way to the next prospecting site Josh, just so happened to spot a new construction site on the corner of the I-440 beltline and Glenwood Ave.  So we took the next exit and found it straight away.

All the signs of alpine-type fissures where we find our crystals were there! Yes! Quartz rock could be found on the surface! Yes!! Where were the crystals? Not here. 

If you look at the last two images, there was one particularly large fissure where there was some very minor but ugly crystallization but that was the best we found there. It may be worth checking again after some good rain but I would be satisfied crossing this one off the list.

Heck yeah! Atleast now you don't have to drive by the spot for the rest of your life
wondering just how HOT that spot was and kicking yourself for not checking it when you had the chance!
I haven't seen the Glenwood spot. I'll give it a second look for you sometime.
We checked New Hope Road, Knightdale and Clayton and found the same as you.
Unfortunately we were too late to those spots to get a good look.
But we're supposed to get more rain this week.

Let us know what you find, Dan. And bring your camera!
