- Castle Rock Natural Area Preserve (dnr.wa.gov)
On this preserve, dramatic basalt cliffs, canyons and tabletop mesas support unusually well preserved examples of eastern Washington’s shrub speckled grasslands known as shrub-steppe. A diversity in soil and habitats on the preserve provide sites for six distinct plant communities identified in the State of Washington Natural Heritage Plan. Threetip sage brush, big sagebrush, bluebunch wheatgrass, needle-and-threadgrass, and Idaho fescue are the main species represented in these habitats. On top of the castle, alkali-tolerant wildflowers and grasses grow in bands around a shallow, seasonal (vernal) pond which gradually dries up during summer.
- North Queen Anne Drive Bridge (Wikipedia)
The North Queen Anne Drive Bridge is a deck arch bridge that spans Seattle’s Wolf Creek. The 238 ft (73 m) long steel and concrete structure was built in 1936 to replace the previous wood-constructed crossing. It serves as a connection between the Queen Anne neighborhood and the George Washington Memorial Bridge that carries State Route 99. The arch is unusually high and uses a minimal number of supporting members. It was designated a city landmark on December 28, 1981, because of its unique engineering style.
