I recently posted this elsewhere and got a few mixed replies on what it could be. Be as detailed as you can be please, I'm a bit of a newb and would like as much info as I can get to learn

Sorry, I completely forgot to add location.
We found it high up near a large reservoir in the Willamette National forest in Oregon. Can't give any information about the rock, it's a softer red rock.
Your response nearly mirrors one of the ones I've gotten so far, and from what I've gathered I agree. However, I have searched for hours and haven't found any info on what mineral the drusy is and I'm quite curious. I haven't seen anything like it before, it's one of my favorite pieces from my first hunt.

I guess you could grind and polish a face in the red rock on the side
you want to display if you want to. Might make it look better.
It is a nice specimen but not really cutting material like the world famous
jaspers and agates that come from just east of there from Bend to Deschuttes.
What a wonderful area to live if you're a rockhound!
If that is your first found and kept, collected as a rockhound "rock specimen".
Thee specimen that made you want to know more and begin your subsequent hours and days and years
of pouring over maps and old geological and mineralogical records in the name of not only knowledge, but science,
then it will never be "worth" as much to anyone else as it is to you. 

Since we're getting all long winded here;
sounds like the red rock could be an argillite. it would be interesting to know when t formed.
you can try and compare the drusy to Prehnite but I would still guess it is quartz
that is included by whatever the bluegreen layer is underneath it.
Chlorite? Serpentine?
In different light and at different angles you will get different amounts of color
"reflecting" in the druse.

Google "Geology of the Western Cascades" to start
and have a good time.
