- Camas Meadows Natural Area Preserve (dnr.wa.gov)
Located in the Wenatchee Mountains of north-central Washington, this 2,018-acre preserve contains the largest known population of two plant species, Wenatchee Mountains checker-mallow (Sidalcea oregana var. calva), which is federally listed as “endangered,” and Wenatchee larkspur (Delphinium viridescens), state-listed as “endangered.” These two species are known to exist only within a portion of the Wenatchee Mountains. The preserve is made up of lush meadows dotted with aspen groves and surrounded by ponderosa pine and fir forests.
- Rhombus (Wikipedia)
In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a “diamond”, after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge, though the former sometimes refers specifically to a rhombus with a 60° angle (which some authors call a calisson after the French sweet – also see Polyiamond), and the latter sometimes refers specifically to a rhombus with a 45° angle.
