Editing San Juan Islands (section)

===Shipping===
The San Juan Islands are surrounded by major shipping channels. Haro Strait, along with Boundary Pass, is the westernmost and most heavily used channel connecting the Strait of Juan de Fuca and the Strait of Georgia. It is the main route connecting the [[Port of Vancouver]] and other ports around the Strait of Georgia with the Pacific Ocean.  Haro Strait joins Boundary Pass at Turn Point on Stuart Island, where a major navigation beacon, [[Turn Point Light]], is located. Strong, dangerous [[rip tide]]s occur near Turn Point, as well as near the northern end of Boundary Pass, between [[Patos Island Light]] on [[Patos Island]] and East Point on [[Saturna Island]].<ref name="nauticalcharts.noaa.gov">[http://www.nauticalcharts.noaa.gov/nsd/xml2html.php?xml=coastpilot/files/cp7/12.xml Strait of Juan De Fuca and Georgia, Washington; Chapter 12 - Coast Pilot 7 - Edition 43, 2011] {{Webarchive|url=https://web.archive.org/web/20201127170058/https://www.nauticalcharts.noaa.gov/nsd/xml2html.php?xml=coastpilot%2Ffiles%2Fcp7%2F12.xml |date=November 27, 2020 }}, [[National Oceanic and Atmospheric Administration|NOAA]]</ref>

Rosario Strait is also a major shipping channel. More than 500 [[oil tanker]]s pass through the strait each year, to and from the [[Cherry Point Refinery]] and refineries near Anacortes.<ref>{{cite book |last=Scherer |first=Migael |title=A Cruising Guide to Puget Sound and the San Juan Islands: Olympia to Port Angeles |url=https://books.google.com/books?id=RDGbLROMn-AC&pg=PT202 |access-date=2011-06-23 |year=2004 |publisher=McGraw-Hill Professional |isbn=978-0-07-142039-6 |page=202}}</ref> The strait is in constant use by vessels bound for Cherry Point, [[Bellingham, Washington|Bellingham]], Anacortes, and the San Juan Islands. Vessels bound for British Columbia or Alaska also frequently use it in preference to the passages farther west, when greater advantage can be taken of the tidal currents.<ref name="nauticalcharts.noaa.gov"/>
