This specimen seems highly unlikely from mesa county.

Specimens from there are usually much smaller topping out at a few cm.

larger crystals from that area get paler in color also.

Maybe Red Feather lakes?

Besides how do you get Amethyst Queen Claim, Copper Creek District, Unaweep Canyon, Unaweep District, Mesa Co., Colorado, USA from a label that only says Whitewater, Mesa Co., Colorado?

It's not entirely impossible that this is from the Unaweep area. It may have come from older (perhaps a lot older) material than that currently seen in the market which is in the form of pale purple druzy crystals typically associated with green fluorite. When we had the 75th anniversary celebration of the Colorado Mineral Society a while back, people brought in examples of the best finds from club outings in the past 75 years. One example that was brought in was a really intense purple amethyst cluster from Unaweep that reminded me of some of the stuff from Thunder Bay.


The labeling on the specimen for the photo compared to the locality given is a mess though. Without any labeling it sure looks like Red Feather Lakes material right down to iron oxides coating some faces.
