unknown plant from Montana

Can someone identify the plants in the attached image? This was growing on vertical limestone on the approach to HogBack Mountain, east of Helena, Montana. The plants were upwards of 3 feet across. Amazing cliff-hugging adaptability. No close-up, as I had to use a telephoto to pull in the plants.

Hi, Jim!  Welcome to the site!  Nice to see you posting here.

I'd suggest your mystery plant may well be the famous Kelseya uniflora:


Calgary, Alberta, Canada - Zone 3
-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
