Kanab Yucca in the Dunes

This is a very rare variety of yucca that only grows in a limited area of southern Utah called Kanab yucca or Yucca angustissima - Engelm. ex Trevir. As these plants and other grow, the wind blown sand piles up around the plants and eventually, they form a mound of sand that is partially stabilized by the roots of the plants.
