On my trip aboard the Passing Cloud we visited Burnaby Narrows (Dolomite Narrows on the chart) a couple of times.
It is on the west side of Burnaby Island in Gwaii Haanas, Haida Gwaii.
The narrows have a fantastic concentration of intertidal and subtidal life, encouraged by the high water flows with concentrated nutrients.
There is so much life living on the ocean floor that it is not possible to walk on the beaches at low tide.
The best way to see the cornucopia is to bring examples to the boat to look at and then return them to their homes.
Kayaks with windows in the floor are another good way – the Passing Cloud carries two of these , one of which is seen here.
On the Passing Cloud the first mate was responsible for retrieving specimens for the passengers in the zodiac to look at.
On one trip a passenger had brought her wet suit and joined him.
