Marker Poles is located in the Southern Channel Islands. This site is near the San Nicolas Island/Freighter dock Mussel Watch site and is not accessible by the public, as it is on navy-owned San Nicolas Island. Visitation to this site is limited to fishing and tidepooling navy personnel and a handful of researchers. This gently sloping site consists of moderately uneven terrain, containing few cracks and folds.
