The Carl S. English Jr. Botanical Gardens (7 acres) are botanical gardens located on the grounds of the Hiram M. Chittenden Locks at 3015 NW 54th Street, Seattle, Washington.
By following the curve of the handle from Alioth (ε) to Mizar (ζ) to Alkaid (η), one reaches Arcturus (α Boötis) and Spica (α Virginis). A mnemonic for this is “Arc to Arcturus then speed (or spike) to Spica.”
