Close up of fossil ferns petrified in a stone slab
A thousand or more years ago, natives inhabited the lower elevations around the San Francisco Peaks of Northern Arizona. In an area so dry it would seem impossible to live, they built pueblos, harvested rainwater, grew crops, hunted game and raised families. Today the remnants of their villages dot the landscape along with other artifacts such as this obsidian projectile point from the Sinaguan era; about 500AD to 1450AD. Although commonly called an arrowhead, the point was probably not attached to an arrow or shot from a bow, a weapon not thought to be used by the Sinagua. More likely it was affixed to the tip of a spear and thrown to strike and kill game animals. It is unlawful to remove artifacts, such as this point, from a native site. They may be examined but must be returned to their original location. This projectile point was photographed at Sandy Seep in the Coconino National Forest near Flagstaff, Arizona, USA.

Caltha palustris, commonly called Marsh marigold, is a rhizomatous perennial of the Buttercup family that is native to stream margins, marshes, swamps and wet meadows. The common name, marsh marigold, is only descriptively accurate as to this plant’s habitat, because it neither looks like, nor is related to, marigolds, which is Aster family. It typically grows 12-18” tall on hollow, branching stems. Bright yellow flowers with 5-9 deep yellow petal-like sepals bloom in winter and spring (February to June).

Euphorbia cyparissias, or Cypress Spurge, is a perennial herb with erect stems, narrow and needle-like leaves, and yellow, crescent-shaped glands on the rim of its cup-shaped flowers. The flowers appear in spring and early summer, consisting of lime-yellow bracts that slowly fade to red-orange as they mature. It spreads by rhizomes and can be quite invasive.
