Weavers Needle is a 1,000-foot-high (300 m) column of rock that forms a distinctive peak visible for many miles around. Located in the Superstition Mountains east of Phoenix, Arizona, Weavers Needle was created when a thick layer of tuff (fused volcanic ash) was heavily eroded, creating the spire as an erosional remnant with a summit elevation of 4,555 feet (1,388 m). It is set in a desert landscape of cactus and mesquite bush, with large Saguaro cacti particularly prominent.
