Help ID this flower

Can anyone help ID this flower? I found it a couple of weeks ago near Grand Lake, CO. Thanks

Perhaps Saxifraga aizoides – Yellow Mountain saxifrage, Yellow saxifrage.

Looks like a species of Sedum to me. But not one native to England.

Thanks to both of you. These are good suggestions. My best guess so far is Yellow Stonecrop which is a Sedum species but I haven't found any examples with bright red stems and red in the blooms. That's what seemed so unusual when I made the image. The Yellow Mountain saxifrage also seems a good choice. Both appear to grow in rocky soil in alpine areas; exactly where I found mine. Guess I'll keep working on it. Maybe someone from Colorado will know for sure.

My wife the botanist says sedum, not saxifrage, though she doesn't know which species. Could be a mutant of the Yellow Stonecrop, I suppose.

That central stem says Sedum to me.

Habitat? Dry: Sedum. Wet: Saxifrage.

Thanks again to everyone. Doing a keyword search on Yellow Stonecrop found one very much like mine but not quite so red, so I'm going with that.
