Harris Point long-term survey overview

Harris Point is dominated by consolidated angular metamorphic bedrock, and the area surrounding the site is comprised of a mixture of consolidated bedrock and boulder fields. There is a small islet offshore from the site that rises 6-8 m high that affords the site some protection; however waves have been observed breaking over the islet. High rocks on the outer edge of the site give further protection from the prevailing NW swell.
