River Tour: Quartz Boulder

Quartz boulder and the narrows

You will see a large quartz boulder, wedged into a narrows in the stream formed by a solid rock ravine and look downstream into the rocky narrows. This stretch of stream is the barrier to the upstream dispersal of many species of fish and forms the border between a more diverse community downstream and a less diverse community upstream.
