- Siliceous rocks are sedimentary rocks that have silica (SiO2) as the principal constituent. The most common siliceous rock is chert; other types include diatomite. They commonly form from silica-secreting organisms such as radiolarians, diatoms, or some types of sponges.

The former Wayne Golf Course in Bothell has now been converted into an urban green space, and provides an 89-acre open area for visitors to hike, picnic, play field games and enjoy nature right next to the Sammamish River. And don’t worry about flying golf balls – golf is no longer allowed in the area.
