Closeup of a blocky, reddish sandstone rock covered in mottled green and gray lichen with a few small patches of snow trapped in the shadowed corners of the rock.

Dozens of white, spherical, puffy seed heads on the tops of dried wildflower stems standing on a hillside among tall, dried brown grasses alongside a hiking trail.

Bright red, somewhat conical seed heads at the tops of bare sumac stems growing on a hillside that is covered in dried vegetation plus a few light patches of snow in the shadowed areas of the hill.

Looking across a low, wooden post fence toward some uptilted rock formations known as the Flatirons, which are in the distance beyond some rolling hills covered in dried brown grasses and dotted with a few dark green pines trees. A low-angle, late autumn sun is hanging in the afternoon sky just above the rocks, along with a few high, thin clouds showing a bit of colorful iridescence as the sunlight refracts through the ice particles in the clouds.
