Hey Rebecca from Over the Great Divide, Happy New Year!
Yes, I only made it out the one day last year, but it was a good time.
All the points found that day, other than the quartz and quartzite,
were one form of the rhyolite or rhyodacite we have around here.
I wouldn't expect you to be seeing much of it in your area.
Now here's where you get more than you bargained for.
Remember that "green" color is the oxidized patina on the rock and
not what the material looked like when the point was made.
Of course all the points I found that day were Woodland period arrowheads
so no more than around 2000 years old and less. So they have had less time to oxidize.
Look at the broken end of the point on top in the first pic below
and you can see the dark creamy material the whole piece was
and the thick rind of oxidation that has developed in the 8000 years since it was made.
In the second pic below are two scrapers with different degrees of oxidation.
The one on the left is a more ancient flake than when someone decided
to use it as a scraper, creating the "freshly broke" dark edges.
That scraper appears to have been made as a spokeshave-type
for smoothing wooden shafts. The edges look so fresh it could've been a farmer smoothing his axe handle.
Somebody picked up an old flake and made a scraper out of it at sometime.
