Summit surprise: a glacier buttercup

An epic day for me: 8 and a half hours. MTB from home, leave the bike, climb into a wild and remote valley, acend to the summit of Piz Uter (2907m), traverse the ridge, two more summits, refind the lower trail, then bike and home.
I saw a young deer by the stream, a family with young chamois, a rock ptarmigan, a squirrel, marmots, plenty of birds but not a soul on the hillsides once I'd gone 20 mins from home. That's solitude.
Then there were all the plants. The one I blipped was abundantly resplendent on the rocky flat topped summit. Thanks to TonyG for the correct identification.
In the extras I have put my favourite alpine (alpine toad flax) and a couple of views on my route, the latter of which looks into the national park.
