These were late in 2015 at Loveland Pass: July 27, 2015. The base is striking.

Note the interesting looking base. The next shot shows the base in more detail, which also shows the red runners that define this flower.

Next one is from July 24, 2016, above Loveland Pass; a bit early given this year’s late snow, but a couple were out.

The next shot if from Hoosier Ridge, just below top of first bump, but below the false summit I think). July 16, 2017.

On July 8,2018, high above the east side of Hoosier Pass, I found several. The one below used a paper backing to eliminate the background.
