- In geometry, an Archimedean solid is one of 13 convex polyhedra whose faces are regular polygons and whose vertices are all symmetric to each other. They were first enumerated by Archimedes. They belong to the class of convex uniform polyhedra, the convex polyhedra with regular faces and symmetric vertices, which is divided into the Archimedean solids, the five Platonic solids (each with only one type of polygon face), and the two infinite families of prisms and antiprisms. The pseudorhombicuboctahedron is an extra polyhedron with regular faces and congruent vertices, but it is not generally counted as an Archimedean solid because it is not vertex-transitive. An even larger class than the convex uniform polyhedra is the Johnson solids, whose regular polygonal faces do not need to meet in identical vertices.

Liberty Bell Mountain is located in the North Cascades, State of Washington, United States, approximately one mile south of Washington Pass on the North Cascades Highway. Liberty Bell is the most northern spire of the Liberty Bell Group, a group of spires that also includes Concord Tower, Lexington Tower, North Early Winters Spire, and South Early Winters Spire.
