Forget-Me-Nots, rare white variation (Eritricheum argenteum)
As far as I know, these are not in Summit County (false, see below). Jane Hendrix tells me they have been seen in the Collegiate Range on Mt. Princeton. <http://colorado14ers.com/php14ers/tripreport.php?trip=4527&start=6880&cpgm=tripmain&ski=Include>
These are at the summit area of Mt. Evans.
It was nice to see a patch of blue and white right beside each other.
Finally, thanks to Pat Taylor, I found a patch of these in Summit County. These are near the west end of the westmost (the third) Loveland Lake just west of Loveland Pass. June 24, 2018.
And these are from rocky and damp terrain at about 13300 feet just S of the Mt Evans road (July 9, 2023).
