Volcanic cones or cinder cones result from eruptions that explode mostly little pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up about the vent. These can be relatively short-lived eruptions that create a cone-shaped hill maybe 30 to 400 meters high. Most cinder cones explode only once. Cinder cones may form as side vents on better volcanoes, or occur on their own. Parícutin in Mexico and Sunset Crater in Arizona are examples of cinder cones. In New Mexico, Caja del Rio is a volcanic field of over 60 cinder cones.

Spring Wildflower Pilgrimage
Each spring, the park hosts the Spring Wildflower Pilgrimage, a week-long festival of programs and guided walks and hikes that explore the wondrous diversity of life in the park.
In summer the display continues with brilliant red cardinal flowers, pink turtleheads, Turk’s cap lily, small purple-fringed orchids, bee-balm, butterfly-weed, black-eyed susans, jewel weed, and many others.
By late summer and through the fall, goldenrod, wide-leaved sunflowers, tall ironweed, mountain gentian, monk’s hood, coneflowers, and numerous varieties of asters begin to bloom. Purple umbels of sweet Joe-Pye-weed stretch towards the sky and can reach heights of ten feet.
Trees and shrubs bloom throughout the year too. From February through April the flowers of red maples paint the mountains with a wash of brilliant red. Showy trees such as serviceberry, silverbell, flowering dogwood, redbud, Fraser magnolia, and tuliptree soon follow. Later in summer sourwood, a tree prized for the honey that bees produce from its small bell-shaped, white flowers, begins to bloom. The year ends with the yellow flowers of witch-hazel, which blooms from October through January.
Closer to the ground on shrubs, the small, bight yellow blossoms of spicebush begin to bloom in February and are soon joined by sweetshrub, dog-hobble, and flame azalea. The park is famous for its displays mountain laurel, rhododendron and flame azaleas. The lovely pink and white flowers of mountain laurel bloom in early May through June. Catawba rhododendron, which lives primarily at elevations above 3,500’, reaches it peak of bloom in June. Rosebay rhododendron is in bloom at the lower elevations in June and at mid-elevations during July. Flame azaleas bloom at the low and mid-elevations in April and May. On Gregory Bald the colorful display peaks in late June or early July. On Andrews Bald the peak is usually in early July.
