- Beacon Hill overlooks downtown Seattle from the southeast and is distinguished by the 16-story Pacific Medical Center that rises from its northern end. The ridge extends southeast from First Hill between the Duwamish River and the Rainier Valley and rises to 350 feet in elevation. As close as Beacon Hill appears to downtown Seattle, geography has worked to keep the neighborhood distinct.

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.
