- The city of Kirkland, located on the northeastern shore of Lake Washington east of Seattle, is named for Peter Kirk (1840-1916). Kirk was a British steel industrialist who originally envisioned Kirkland as a bustling steel town. Kirk’s plans didn’t materialize. Nevertheless, Kirkland has become by the twenty-first century a thriving suburban community of almost 50,000 people.

The Siderian Period ( /saɪˈdɪəri.ən, sɪ-/; Ancient Greek: σίδηρος, romanized: sídēros, meaning “iron”) is the first geologic period in the Paleoproterozoic Era and lasted from 2500 Ma to 2300 Ma. Instead of being based on stratigraphy, these dates are defined chronometrically.
