}}Claytonia megarhiza is a species of wildflower in the Montiaceae family known by the common names fell-fields claytonia and alpine springbeauty.[2] It is native to western North America from northwestern Canada to New Mexico, where it grows in rock crevices and talus habitats in subalpine and alpine climates. The species is known from summits and slopes of North America's highest mountains including the Redstone Mountains of the Canadian Northwest Territories, disjunct south to the central and southern Rocky Mountains reaching a southern limit in the Sangre de Cristo Mountains. The specific epithet megarhiza is Greek for "large roots".[2]

This is a perennial herb growing from a thick, scaly caudex topped with a stem {{cvt|5–25|cm|sigfig=1}} in length. The fleshy basal leaves form a dense rosette around the caudex. The leaves are red when young and turn green as they slowly produce chlorophyll.[2] The inflorescence appears within the patch of leaves. It is a dense cluster of two to six white or pinkish flowers. Each petals reaches {{cvt|5–20|mm|sigfig=1}} in length.
